i'm currently trying out a few different things and hit a wall when I was trying to get the rgb value of a color in a palette: enter image description here

I'm looking for the RGB Value of one of the colors in this palette, and i want to get it by python and not just by "what slot is active" but by some sort of ID/Name, my next idea was to go to the Blender File API and look there for the Datapath of the individual color to get an idea how i would need to write my script, however right clicking on it there, does not reveal the usual feature to "copy Data Path" so i suspect that the information is stored somewhere deeper and that i need to access it in another way.

enter image description here Sidenote: It would be really great if we were able to Change the name of the individual colors here and i think that is something that is planned.

My final goal would be to get the color and with that set the color of a material on an object, the last part of it i already got down.

Has anyone an idea how i could get the vaulue? I was only able to get the data path up to the Palette itself:

bpy.data.palettes["PaletteTest"].name

But not on the values it contains.

Palette has a colors collection.

Example of displaying and creating palettes. How do i create Palette UI object

Add a new palette,

>>> pal = D.palettes.new("Test")

The palettes color collection holds objects of type bpy.types.PaletteColor. The color is its PaletteColor.color property

give it 10 random colors.

>>> from random import random
>>> for i in range(10):
...     col = pal.colors.new()
...     col.color = (random(), random(), random())
...

All the palettes in the file (just the new one for example)

>>> for pal in D.palettes:
...     pal.name
...     
'Test'

Get that particular palette, will be None if it doesn't exist

>>> pal = bpy.data.palettes.get("Test")

display its colors..

>>> for col in pal.colors:
...     col.color[:]
...

  • $\begingroup$ So bpy.data.palettes.get("PaletteName".colors returns a list/array with all entries in it, how would i get a specific one from that, like the fifth as an example? $\endgroup$

    $\begingroup$ AFAIK the colors aren't assigned name. Index by number pal.colors[0] is the first, etc. & foo.get("bar").prop defeats the purpose, throwing an error if foo.bar is None. Instead if not pal:. $\endgroup$

  • $\begingroup$ Ah okay, i think with the value that is returned its not possible to just straight put it into the value of an RGB Node ... .nodes["NameOfNode"].outputs[0].default_value = (bpy.data.palettes.get("PaletteTest").colors[5]). I get an error doing that : ValueError: bpy_struct: item.attr = val: sequence expected at dimension 1, not 'PaletteColor' $\endgroup$

    $\begingroup$ r, g, b = pal.colors[4].color is the (r, g, b) value given to the 5th color. (ie Use the color attribute as shown in answer) Some nodes may require an alpha, default_value = (r, g, b, 1) $\endgroup$
