These markers are vibrant and cost effective. Like most markers, these do bleed so you have to be careful when coloring by the outlines. I think they do a decent job at blending different colors together, you just have to be quick about it. And these markers are capable of creating gradients by overlapping. As a newbie with coloring with alcohol based markers, these are a great set to use and practice with! Another thing to note is that the fluorescent markers are dry and grainy so it is best used as a highlighter.
