I have a deep blue sky and a bright yellow sunset setting over a nature scene, but when painting in the yellow sunset and fading it to the blue sky I end up with a lot of bold greens that are noticeably out of place.
How do you fade colors without getting the combined color? I'd like to fade a yellow to a blue without getting green in the middle. I assume the concept would apply to any two colors, though.
This may not be the best example image, but here you see very bold blues, and very bold yellows without mixing into a bold forest green anywhere in the sky.
