Material Will not show white

I can do green, orange and blue. But when I set it to white it just goes gray.!? Material is applied via layer.

Hello- the environment is turned down to .30, so the light is quite dim - it looks wrong becuse your background is bright, implying lots of light, but there isn’t; if you put a gray material on the ground plane, you’ll see it looks darker still and the paint starts to look whiter again by contrast, but it is still in low light.
