I used these water color pencils for these cards:
and these cards too!
The brightness of the color depends on a number of things. You can color just the outside, with a fairly heavy line, or you can color the whole thing, lighter, for a more soft/pastel color. You can use 2 different pens to soften the coloring. Both the Aqua pen and the blending pen work perfectly! (I used the blending pen on all of the cards you see above)
