Dark colors are displayed brighter and greyer.
I've seen other people complain about this as well in #unrealengine irc. This picture explains it all:
Its a blueish black, and even bluer and brighter colors that are darker than that preview appear like that as well...
Ive turned off every kind of post processing including tone mapping and it makes no difference. The material itself is unlit.
I did a bit more research, and it turns out that the sRGB channel should be set to true, Specifically on this documentation page: https://docs.unrealengine.com/latest/INT/Engine/Content/Types/Textures/Properties/index.html it discusses the purpose behind the sRGB channel and its' effects. As such it seems that the channel is working correctly, and the reason there is no significant difference between the constant three vectors is that this is meant specifically for textures and their gamma correction. This is not precisely true, however, if your color setting is done in c++, did you set your color in the editor or in c++ specifically?
