review color palettes

[emillipede]

each view has defined color palettes. the colors and scales could use a little work

could we group tree colors by taxonomy (eg all pea species are different shades of the same color)?

(right now, the palettes for family and species views are automatically generated)

if you're new to the project: please take a look at the colors and let us know which palettes do and don't make sense to you!
