I tried looking through the code to find where compound colours are defined, but I got a bit lost. @TheCreator any chance you could give the hexadecimal or RGB colours for each?
While giving all gaseous compounds the same icon looks nice, I don’t think it’s a good idea since it will remove a lot of the distinctiveness we want to give each icon. Similarly, those which are just a bunch of circles will need to be different enough to others to make it clear at a glance which is which. I believe carbon dioxide is already in the code as dark blue (someone correct me if not), but nothing has been decided for nitrogen yet.
As for the icons themselves:
- The protein one is absolutely perfect. Awesome work on that.
- Same with calcium.
- The flame works well for hydrogen, I like it.
- I prefer the third of the oxygen icons, but they’re all good.
- Water is good but could use some more detail (maybe not though, that’s just my opinion).
- Carbon dioxide works but could be more interesting.
- I like the amino acids one but be careful it stays distinct from all the other circle-heavy icons.
- Neither of the glucose icons seem right to me. For one thing the backing circle should be closer to white than grey. A sugar cube could work but the positioning of it seems a bit…off. That might just be me.
- I still have problems with the ammonia icons. In particular the blue atom breaks the colour consistency. I think the fourth one (with one big, textless nitrogen atom) would work if the blue was change to a different shade of yellow.
- Any of the ATP icons could work but they all look a bit rough. I don’t think the 3D works on the lightning bolt.
- If you’re changing oxygen to the second or third option, the nitrogen concept could work.
As for the biomes, I agree shallow ocean is great but hydrothermal vent needs work. If you didn’t know it was a vent you wouldn’t know it by looking at it. It looks more like a patchwork quilt.
