Color Accuracy

As shown in this video, there’s a rather large discrepancy between the color chosen and what’s displayed on the surface. I ‘was’ under the assumption that Unlit materials using colors in the 0-1 range in emissive would show the color as it was chosen without any influence from lighting or glow.

I’m curious as to what’s happening under the hood so that we may more accurately depict colors in the engine.

Thanks for any insight.
