Mixing oils or acrylic colours/shades?

Question

This is driving me completely INSANE!

I'm currently working on a painting of an abbey ruin and I need to mix a colour that looks like old stone, darkish in colour where the air/pollution has darkened the stone.

Here's a pic of what I'm TRYING to paint...

No matter what colours I mix together I can't seem to get the right shade! It's doing my head in! The painting is close to completion apart from adding this colour and some fine details/highlighting effects.

Anyone have a clue how to replicate the colour of old tarnished stone and for it to actually look like the texture of stone?

I've taught myself to paint but there is only so much I can work out on my own, any hints/tips would be greatly appreciated!

Answer 1

I see purple mixed with yellow. This mixture gives you a neutral gray. Make a few mixtures with more yellow/less yellow and use the cooler mixture for shadow area, warmer for sunlit area.

Try to avoid using black paint - it's such a dead colour. if you want a deep shadow tone, mix red & green or orange and blue together instead.

Use a dry brush for the stone texture - squeeze most of the paint out of the brush and drag the brush on its side across the surface so it deposits paint only on the textured surface of the paper, letting the colour beneath show through.

have fun!

Answer 2

The texture you should be able to get with your brush strokes. For your color, I'd mix up what you used for the lighter parts, then add just a touch of black to make it grey.

Answer 3

just try real hard,as my art teacher says,if you need it to be exactly the way it is then tack a pic. of it.
