Hi @Trendygirl, what you do is:
Drag out a Set Text block-
Then on the left you'll see the purple "Random __ to ___" block. Drag that out into the Color space instead-
And then you'll find that you'll be able to tap on the Random block and edit its numbers
Glad it helped! No need to give credit, it's just a little trick You can do the same thing with values as well and drag Values from another block into a Color space too.
But there is a random color thing at the bottom of the cool picker too
Random color picks one from all the colors. @Trendygirl wants a color from a certain set of colors only.
