I'm having an issue that is very possibly the result of a simple misunderstanding. I've prepared a short video describing the issue, please watch at x1.5 - 2.0 speed.

Essentially, I do not understand why a color swatch represented in a texture should respond at a different sRGB value than that same color rendered from a Corona Color map.

I want to emphasize that this is probably a trivial oversight and I apologize in advance, but I am trying to understand.

Check if material has enabled reflection.

Are you sure? I've just downloaded dubcat's file to see for myself and his materials has reflection enabled. So, unless you modified the file, my suggestion still stands - check if material has enabled reflection. If it does, disable it and run the test again.

Do you mean Reflection: 1.0, Glossiness: 0.0, or literally reflection channel disabled in maps rollout? I *just* downloaded the scene from the post described in the video, see attached.

I tried additional tests and even when every channel of the shader was disabled, except for diffuse, the surface registered contrary to the expected value.

Disabling channel in maps rollout, only disables texmap if it's plugged in, but not disables reflection. You need to set reflection level to 0 or set it's colour to 0, 0, 0

Quick question, why did the materials in Dubcat's .zip open with reflection enabled - I assume the reflection was supposed to be disabled?

Maybe it was developed in a previous version of Corona where the materials defaulted to reflection 0.0 (?)
