Compound Colors

[Atrox]

I agree with everything except

@NickTheNick

Hydrogen Cyanide - Although this is typically colourless, since Ammonia is light grey and Glucose is white we could make this light brown, light purple, or light orange?

Hydrogen cyanide could be a bright color to help players identify it as dangerous. If I recall correctly, the shocking pink dragon millipede secretes hydrogen cyanide. It could be a hot pink compound.

@NickTheNick

Lactic Acid - White and cream and beige are taken, so we could make this light brown or light orange?

I didn’t see green on your list. Lactic acid could be an acid green or a light green.
