Re: for those using digital photo references
Hi there, red is a very dark colour. I've seen a colour chart with pure Alizarin Crimson (oils) rated as an 8 on a nine point scale. Permanent Rose was a 7, and Chinese Red a 6, so also a Cad Scarlet. Cad Orange a 5.
Some say the Chinese Red is a very pure red, with no bias.
To distinguish black from red in b/w photo, one has to shine an extremely bright light on, for example, a red business card with black text, in order to photograph them as separate values.
So, if the bird looks black, I'd say go with the darkest pure red you've got, and use blues and greens a purples for shading and toning down, saving the red for the lightest parts.
Hope this helps.
