However, there's no "Art Discussion" Board, so where is this fellow going to talk about blending colours with anyone?
It's either post a picture and ask for critique or post critique for someone else's picture. Doesn't exactly sound like a welcoming art collective does it? hahaha.
To be completely honest, anything blends. It just depends on what colours you choose and where you put them.
It's not so much a trick to have colours blend realistically, it's more so improvisation, work and perfection.
All you need to do is practice more and more until you feel as though you're happy with the outcome!
