ASC-CDL stands for the American Society of Cinematograpy's Color Decisions List
It's designed to create a standarized protocol to share basic color correction data across different systems form different vendors. It is a protocol that can be applied to either scene referred linear or log-like encoded imagery. The following outlines scene referred as Blender’...
Using Animation Nodes
Updated for Animation Nodes 2.0!
Method with the Molecular Modifier and CubeSurfer below!!!
Another way to do this is using @Jacques Lucke's Animation Nodes addon. Here is the final result:
And here is a picture of the node setup:
This is done with a Rigid Body Simulation and Vertex Colors. After installing Animation Nodes (linked ...
What Non-Color Data means
Choosing Color Data vs Non-Color Data determines whether or not Blender will color manage your image.
Gamma Correction is a way of compressing color data and is commonly used in many image formats, such as PNG and JPEG. Without getting in to the mathematical nitty-gritty, Gamma Correction raises the intensity of a pixel to a ...
In Blender Render engine you may achieve it using the material nodes.
Being in Edit Mode unwrap your mesh (press U-->Project From View).
Create some materials- basic Orange and Pink materials (the ones you want to blend), Transition (this material'll be used for blending the ones above using material nodes) and Gradient (this'll be used to create a ...
This is not caused by the remote server, amazon, the CPU, the GPU, 1394, or some weird vudu curse. Any computer that is not your local machine will render the images green, because the file has not been been saved correctly to render in a different computer.
Your file is using images as textures, but the images are not packed into the file, or are stored ...
By inverting the RGB channels before splitting them I was able to create a working setup that is also easier to understand.
Here is the new node setup:
There are a few things that can probably be tweaked and improved, but in essence the problem is solved.
It looks like the model is made using technique similar to metaballs in blender. To Create metaballs, in object mode Add > Metaball > Ball, and Add > Metaball > Plane for the surface
That kind of material can be achieved usin position from Geometry node, adding Separate XYZ, plugging z output to Math node set to "modulo" with unconnected socket at 1, and ...
This type of material is super easy to do in cycles. First break down what you want to do.
You want to have a gradient (three color stops).
You want the gradient running along the Z axis.
With that as our objective, we don't even need to touch any UV mapping.
Start by getting a gradient running in the direction you want (Z axis).
There are several ways to ...
Here's my latest render. I'm not fully satisfied with it yet, but it's close.
Here is the node setup:
Click to enlarge.
It's basically an Anisotropic shader with a little bit of straight gloss, then a very light Fresnel component. I then used a stretched noise texture to mix in a very small amount of diffuse (to make some cracks more pronounced) and ...
Light code gets promising results already.I made an example with rigid body meshes instead of particles. Spherical particle will be easy to detect as well since a collision is defined by their distance.
A rigid body simulation.

The RGB values in Blender use a linear color model while the Hex values use gamma corrected non-linear color model.
To convert between these two, you would have to manually do the gamma calculations using the transfer function of your color profile, wich is set in the Color Management section of your Scene – set to sRGB by default.
The excact conversion is ...
Quoting @troy_s, (the creator of the filmic blender's color transform LUTs and config.ocio files)
Is there any difference between this repository and the filmic blender in 2.79?
The default "Filmic" view, which carries on Blender's confused description of what a display is, is actually the Filmic Log Encoding Base coupled with the Base ...
It's easy to demonstrate this effect in Blender. Cycles operates in RGB-only mode. It cannot simulate any colors in the visible light spectrum except for red, green, and blue.
This isn't correct.
The reference space primaries are determined by the colour management system. In theory, any reference space primaries within, or even beyond, the spectral locus ...
The most elegant solution is using color management and a custom matrix to convert the image's color information to a grayscale.
You can easily and non-destructively represent your scene in grayscale without the need of changing materials or affecting the overall quality of the render.
User @troy_s has created a LUT pack and OpenColorIO (OCIO) config that ...
Actually, I figured it out shortly after posting the question.
Instead of using:
I needed to use:
So the final solution was:
activeObject = bpy.context.active_object #Set active object to variable
mat = bpy.data.materials.new(name="MaterialName") #set new material to variable
CMYK and RGB are relative colour spaces, and as a result, individual values mean nothing. In RGB's case, it means the intensity of three lights, a white point colour, and a transfer function which are not specified by the values alone. In CMYK's case, it means four (or more) arbitrary ink colours as well as paper stock and illuminant.
Taken in isolation ...
You can't, not without adding a whole different reference space, and you don't actually want to. The explanation for this is very long winded, and I'm willing to explain, but the short version is as follows.
Proper mixing of colour relies on modeling our real-world of physics. That part includes using linearized systems that orbit around the spectral locus. ...
That's because you are using Object's Texture Coordinates, which determine how an image is placed upon the faces, while you need Object's Cartesian Coordinates.
Texture Coordinates usually vary from one point to the other. Referring to the picture below we can see how the gradient is assigning to each point at the same Z the same value. ...
Blender will generally linearize colors when importing 8bit images. Photoshop does not. Normally, Blender's behavior is correct but in this case you are encoding data here, not colors. You can inform Blender of this and disable the de-gamma step by setting your input color space to "linear" or "raw" instead of "sRGB".
In Cycles a color is just a set of 3 numbers representing the red, blue, and green content of the color. To perform a mathematical operation on a color Cycles splits the color up into its RGB channels, performs the operation on each channel individually, and then combines them back into a Color datatype again.
The Mix RGB node, when set to difference, ...
This is because the math node only deals with single scalar values (note the gray sockets).
See What is the meaning of the color of the node sockets in the node editor?
If you use a node with yellow sockets (Color > MixRGB), it will maintain all the color channels:
I have just created aquick node setup for the animation with Animations Nodes Addon
Basically you put a MBall plane as suggested on the previous answer. Then you pick a MBall and duplicate it wit the instancer node. Then you create a loop with those instance to perform some procedural operations.
Balls are scattered on X and Y via the Randomize vector. To ...
There are a few ways to make the objects fade in the distance like the image you show.
The most realistic would be replicating what would happen in real life: Suspended particles (haze, smoke or dust) would float in the atmosphere limiting visibility of objects in the distance.
To do that in Cycles you can add volume scattering and volume absorption ...
It is possible to do that in Cycles using a Camera Data Node
You must use the output of the View Vector socket, separate it into its components with a Separate XYZ node, then pass its Z component through a Color Ramp node to control what colors you get.
The effect might be hard to see at start because the red color would always be off-camera, but tweaking ...
Watch your albedos. It doesn't matter if you use pure primaries or highly saturated colours; Filmic will desaturate as things get too intense. High albedo will race those values through the roof quickly, leading to desaturation. As Cegaton wisely said, the old adages are pure rubbish based on a lack of understanding regarding view transforms; feel free to ...
You can do this easily with animation nodes in the blender 2.80.
Create a number of instances (with deep copy) and place them using the grid distribution node. Then use the same grid points or vectors to sample the texture with Texture Node, which gives you the color of texture at that point of the grid and by changing the scale of the grid points you can ...
There are a number of reasons, as @tardis-maker suggested in the other answer.
Here are a few more:
Grading. As stated, it can be beneficial to be looking at a display referred view of your final output that covers any number of stops above middle range, properly mapped to the display referred viewing transform
Proper desaturation. Rendering in a scene ...
The key advantage is that it works real-time in the view-port.
Of course all color manipulation could be done once the file is saved.
However having this apply to previews while you're setting up your scene means you can setup a a rough grade, and then build the lighting off of that. This allows you to get a really good idea of where you need more detail in ...
