Been learning a little more about colour theory in level design. So far my goal with these maps was a pretty drab, desaturated look, offset with strong primary colours (red, blue) in very few places. A slight contrast between the orange-ish torchlight and a couple greenish textures managed to sneak in though.
I tweaked the floor tiles to be more reddish now, in order to get the floor to contrast more with the walls. My first attempts came out even more red than this. I reduced the intensity a little because it clashed with the rest of the map. The result is more terracotta than red, but it looks very different depending on the amount of torchlight hitting it. I left the small tiles mostly alone, although I toned down their extremely green hue a little. This gives me both different structures and complementary colours to work with, and I can have them more or less apparent wherever I want.
I think the white brick texture (usually used for stairs here) creates a really nice highlight; I should probably use it a little more.
Anyway, red floor tiles yay or nay? I think yay.
I should eventually go over e1m2rq to make use of the same colour scheme and lighting. Another reason to like the red is that e1m5rq uses the red elder world theme, and this should tie the episode together a little better.
