Welcome to our team Karma Tucker!
Neat thing I figured out:
When created the text in a card, say you upload a PICTURE to the bottom of the card, and you are typing TEXT at the TOP of the card.
You want your TEXT to match a color in that picture - type your text at top, highlight it, choose colors, then MORE colors, that little wand comes up - you can actually instead of choosing on that color wheel, use the wand to grab a color in your picture you had uploaded!
