Someone who used Prismacolors, he told me that the Prismacolor finishing spray used to bring out the color of his work. I never tried that brand yet.

I find the same thing with my watersoluble pencils. Now I make sure that everything looks WAY TOO VIBRANT AND BRIGHT (!) before it dries, to counteract that fading effect. Also, layering, and finishing off with dry coloured pencils works for me.

I’d be very interested to hear if the spray works – please do let us know once you’ve tried it!

I always spray with a gloss clear fixative varnish after completing a car. It gives a nice shine to what is a man made polished object after all. I’m not picky as to any special varnish, I just use a local NZ art shop product called chroma spray (I think..)

Karen, Golden MSA archival spray varnish. She uses several coats of Prismacolour spray fixative before the varnish. Wish I knew how to post the link but I don’t, so you will have to look up Ester Roi to read how she does it.
