Not too dark but enough to trace images from projector.
I love the selection of colors available by Rainbow Dust! I ordered the silver/grey, bright gold, burgundy, teal, sky blue, navy blue, purple, red, leaf green, chocolate brown, and several black pens to use on my cookies. I can't wait to see what others colors they develop to sell. I would to see peach, rose pink, lime green 😃
Hoping with 2nd application the color darkens.
Really easy to use
