Pastels and Future as Filters

Never tried specifically with pastels, but have used future to lay down a thinned acrylic paint colour.  In essence, all you are creating is a tinted gloss coat.  Only problem I can see if using this method on a larger scale is curing time.  Also several layers of future might fill in recessed detail.

Btw, you can create green by combining yellow and blue, or black and yellow - though the latter will be more olive shade.  To those two combinations, adding a little red will produce more earth tone.

Thanks Jack. 

I'd thought of yellow and blue but had no blue either. Black and yellow though, I had and they produced a decent shade of olive. 

Here's some before and after pics....
