Final fixative for Prisma colored pencil drawing
This question might have been asked before but couldn't find enough information. What's the best fixative (to protect and avoid wax bloom) for a prisma colored pencil drawing ? I tried grumbacher final fixative for pastel,pencil, charcoal on a sample colored pencil drawing and felt the white of the paper turned a little yellowish after one coat but the colored part looked ok.
Can you please suggest a fixative which works well with prisma color pencils ?
