How Can You EasilyChoose Grayscale Colours In ToonBoom

Does ToonBoom allow you to choose from a selection of grayscale swatches.

How do I choose or do I have to create the colours myself. The colour picker seems overly complicated and I am sure there must be a simple way to do this.?

I am using Harmony 12 advanced.

Many Thanks in advance

You’ll need to create the palette yourself since the
default palette will have only a few basic colours
at the start.

If you edit colours in HSV mode (as opposed to RGB)
you need simply set the H(ue) and S(aturation) to zero.
Play with the V(alue) setting to get your different grays.
