nice one. love the tree and how surreal its brightness looks..
i have just been painting some red with great difficulty . it takes so many layers to become solid colour and also for some reason i find the tones with reds difficult to achieve. so my question to you, is how have you got that red so bright.?
Thank you for the compliments! To answer your question:
For the bright reds I use cadmium red medium and heighten it with cad yellow plus the tiniest amount of flake white to help with the opacity. The paint is also applied pretty thick.
For the most part tho, it's just a bunch of visual color tricks.
It's nearly impossible to see in the image but I use simple simultaneous contrast in the shadows to make the bright reds look 'brighter'. The shadows are very dark, cool, thin, greens and blues mixed with alizarin. I also change the temperature of the sky around the tree according to what is happening in the tree. i.e. The tree is bright red-orange, so I make the sky cooler and bluer or greener. The tree is cool and dark blue/green/alizarin so the sky gets warmer and steers towards orange.
well thats most ingenious... thanks for that, i can see you are thinking quite a deal while painting, which is really great. the red i spoke of just seemed so bright and powerful, perhaps the fact that it is applied fairly thickly helps..
