Something that's been on my mind since a while...:
Do you AR users mix oil paint and watercolor on one layer?
I ask because.....

Sometimes I like to make my oil brush strokes a little blurry... on canvas (I had been painting with "real" paint more than 10 years...) I used much thinners in order to do that... but somehow, I do not get the same effect in AR using much thinners (I still play around with the thinners, but the effects are different)... so, what I found out, watercolor brush does what I used to do with thinners on paper. So, I use it
With actual physical paint, this was a no-no for me, never tried I just think it wouldn't mix at all as... one uses water, the other oil ... obviously.

So, ... my question above What is your opinion about this?
Each time I mix the two I feel "guilty" . But it looks ok to me

This is NOT a technical question, (technical question => how to do it etc), but a discussion about ... art ethics and art-blasphemy
