Need to be Precise About Colour?
If you have a specific colour, say a corporate identity, you may need to reproduce this colour in as many of your tools and their outputs as possible.
Cradle has a default shipped palette 120 colours. But these may not precisely match your requirements.
Solution
You can tweak the Cradle colours.txt file to change the RGB values to match your colour ident. This colour will now be available in the palette.
So if you need to produce #ColoroftheYear2017 Pantone®’s 15-0343 Greenery if you choose the nearest RGB values, you can.
