What are requirements for ballpoint/rollerball colour pens for art-grade drawing?

Question

Some days ago I saw incredible coloured pen-drawings in some exhibition. I would like to try this medium myself. But before buying some pens I would like to get some requirements for ballpoint/rollerball pens **generally** for art drawing. So, immediate questions are: - Ballpoint vs rollerball? As far as I understand, then the ink makes the only difference between them, rollerballs' ink are more fluid and are coming out more easily. I guess, that rollerballs pens are more appropriate for the art. - What width should I choose? As I understand, then the smallest width - 0.5mm - gives the greatest flexibility and I guess that even thinner pens are not available. - What about color permanence, does art pens have labels for it? - What color palette is advisable? Maybe there are other factors to take into account?This question is about general requirements and it is not about concrete brands. But still - I have heard about Faber-Castell CX color ballpoint 10-color set, but their homepage does not show such product. Nor other larger suppliers of art materials have such category. Maybe there are some advices how to seek further the best pens for art drawing?

Let us put the brakes on for just one minute.

Are you sure you were looking at ink pen drawings.

What you have described sounds a lot like marker work.

Check into markers before you start spending money on pens.
