Trouble with hair`s color

I painted woman`s hair using Phthalo Blue PB15.3 (because I got a lot of perfect Maimeri phthalo) and FBB Carmine PR146 mixture. It is looking nice under electric and room light, but when I put my painting on daylight a trouble appears. Color became too violet, with good value, but it has terrific "aniline" color and "bronzing" effect.

How can I fix this trouble?

I am a novice - noob in a portrait painting

Hi Alex, the difference in how the colours look under different lighting is a tricky problem most people face at one time or another. Obviously under daylight the colours are showing up closest to the way they are and under artificial light you're seeing a restricted version of this because of the spectrum of the lighting.

But since artificial lighting could be thought of as a painting's 'natural habitat' you could decide that that's fine - you work from the perspective of how the painting is most likely to be seen, and if it looks good under artificial light that's pretty much what matters. However, if it's hung near a window you will begin to see some of the problem colouring you've described; plus, better artificial lights (bulbs/tubes with a broader spectrum, or a mix of lights that combine to give this) will probably begin to show the same thing.

As far as the bronzing specifically goes, I'm not aware of any way of really dealing with this directly. On the occasions when I've had the problem myself I've either lived with it or overpainted completely.

Do you know if your colour is off in hue, value, chroma... or all three?

Re: Trouble with hair`s color

I found this:
"The term "bronzing," as used herein, refers to the phenomenon that a printed image has a metallic luster appearance rather than its intended color when viewed at an angle. Bronzing often manifests as a magenta sheen over cyan area fills, and a yellowish to reddish to bluish sheen over gray area fills. Generally, bronzing may be most severe at high gloss areas, and decreases at lower gloss areas."

Bronzing effect disappeared then I add a bit of black paint to my cyan-magenta black mixture. Now I`ll try to avoid very high petroleum colours concentration in the future!

Thank you, Einion. I overpainted all trouble places with glaze layer! It looks better now.
