Here's a tip: severely limit your pallets
Don't use 15 tones of green, have 7 and use the first one or two colours as highlight colours.
Imagine you're layering your work, its
Like water colour, start with your base colour (usually second colour or third colour depending on how many highlights) then build up each layer of darkness.
It's much better to make your own colours for a more unified look to them all.
But explaining that is a whole new conversation, if you want to quickly create very simple hue shifted colour pallets, you can input your highlight colour into
this website and mess with its darkness, hue and saturation values to create arrays of pallets for use.
When hue shifting keep in mind that the colour should always shift into its darker counter part:
Red | —>
| Purple |
Blue | —>
| Purple |
Green | —>
| Blue |
Purple | —>
| Blackish blue |
White | —>
| Yellow or blue |
Etc, bare in mind these are very soft rules and depend on your shading style (these are based off my own shading)

How you shape your shading is up to you.
