Here is a quote form the Luminos Ad about RCR Art
"Resin coated, yes, but with the look and feel of a fibre base paper. RCR-Art has a slightly textured surface on a medium weight white base. RCR-Art is dead matte so it is particularly suited for large prints like murals. This paper is one of the most unique of the Luminos family of papers. A perfect vehicle for "color enhanced" black & white prints much favored by the professional portrait, wedding and child photographers. This paper can be toned and handcolored with any medium the artist chooses to employ. With little or no surface preparation it can be colored with oils, pencils, pastels, airbrush, watercolor and even "magic markers". Available in contrast grades 2 and 3 with an ISO speed of 320. Can be ordered in cut sheets and in roll sizes 42" and 48 " wide X 100 foot. "
As far as the statement that it has "the look and feel of a fibre base paper" I an vouch for that. If it were not for may notes on the back of my prints I would swear they were on fiber and not RC paper. I have never done any hand coloring but this paper looks to be made for it.
