I am just simply baking the base color of my mesh into an image. However, the baked image is noticably lighter by around 10%. Why is this the case?

$\begingroup$ Yes weird, I can put my finger on why it doesn't bake the good color (switching the Color Management from Filmic to Standard doesn't fix the problem) $\endgroup$– moonbootsCommented May 22, 2022 at 7:51

2$\begingroup$ Seems like you have a touch of "Sheen" value in your Principled BSDF. Try to switch it off. $\endgroup$– Serge LCommented May 22, 2022 at 9:09

Principled BSDF has a lot of additional inputs which can alter final look, in this case it was 0.01 value of Sheen.
For baking diffuse color pass it's easier to use simple Diffuse BSDF, thus keeping initial color and making original shader's settings untouched.

A slightly easier way is to connect the color socket you want to bake directly to the Material Output, and bake the Emit type. You also don't have to worry about unchecking Direct/Indirect.
This works because when you connect a color socket (yellow) to a shader socket (green), it's as if there's a default Emission shader node in between.
The same method will work for a "dumb bake" of any color socket of course, not just Base Color. (If you want to dumb-bake a scalar instead, try putting it in a Principled's Roughness socket and baking the Roughness type.)

$\begingroup$ Interesting... What is "dumb bake" please? If it is not just the Base Color, what else color is included in the baked image please? $\endgroup$ Commented Aug 31, 2022 at 4:17

$\begingroup$ By "dumb bake" I mean just the plain value coming out of the socket gets put in the texture, nothing "smart" like shadows, lighting, etc. $\endgroup$– scurestCommented Aug 31, 2022 at 4:39

$\begingroup$ Oh, you mean the raw or original color, which is un-processed or un-edited by any middlemen. Thanks! $\endgroup$ Commented Aug 31, 2022 at 4:45
