These color decently and blend pretty well, I attached a few images of stamped images I colored so reviewers can see the blend and vibrancy. I took off one star because 1. The color choices are limited and the numbering scheme doesn't seem to follow a pattern and 2. Some of the markers are very juicy and the ink gets everywhere, even places you don't notice and it smears. Better than being dry though, which has been my experience with other "affordable" alcohol markers, and these are much more affordable than the name brand markers.
Overall, they do a good job and are easy to use. They don't bleed too much, other than the very wet ones. I appreciate the swatch cards that are included.
