Review on Faber Castell Pitt Artist Pens Assorted Painting, Drawing & Art Supplies by Lee Reyna

I love thin brushes and look forward to using them. However, I would prefer if all the buttons were greyscale when there were only 4. The remaining 2 are black and dark indigo. 4 current shades of gray: Cold Gray I, III, IV and VI. There are so many differences between I and III that I would wish for II to be a better gradation. Numbers III and IV are very close together. Number VI and Black have a good separation. Dark Indigo is a beautiful, very dark blue that is noticeably different from black (at least on the paper I tested it on). However, I would have preferred number II to have been included in the set rather than one of these.
