How do I paint white?
Hi. I recently picked up some watercolour pencils to start learning colour. I got the reference from Pinterest and I really want to try painting something with warm and cool colours. But I ran into a couple of problems.
First, I don't know how to paint white. I tried using burnt umber and vermilion or ultramarine but it looked like a muddy piece of cloth, so after trying a few times, I switched to raw sienna and dark violet for the warm parts, and blues for the cool parts. I kinda like the final result, but it looks like a colourful piece of cloth, not a white cloth with warm and cool parts.
My second problem is I don't know how to convey colour temperature better. In the reference, the lit slice looks really warm and glowing, and the dark slice looks cooler, but I don't know how to convey the same effect.
I'd like to paint it again, to try and get my painting to have a similar feel to the reference. What should I work on? I also attached some swatches I made of the colours I have. I'm using aquatone watercolour pencils.
I'm new to watercolour pencils and colour overall, any tips and advice would be appreciated!
