Colour shift when mixing with titanium white

Using the information from GOLDEN about the colours (LAB space converted to RGB and HSV) from their paints from the tube and tinted to 40% reflectance of white (used for lightafstness testing) I was able to show visually the colour shift that occurs. The very dark and very light values are hard to get the hue reading from so this is maybe why PB60 and PV23 show such a large shift.

Might be useful to some people anyway

Re: Colour shift when mixing with titanium white

Very interesting how different pigments hue-shift in opposite directions, some significantly.

Theres a YouTube vid showing the different hue-shifts and tinting strengths of Michael
Harding lead white, zinc and titanium white by Vicki Norman. Its rather striking how the same yellow, red and blue paint samples shift in hue and chroma when tinted with different "white" pigments ...not just in value.

I think that many artists underappreciate the effect that white paints have even though it's often half or even three-quarters of the paint on their canvas. As a watercolorist, i used to not think much in terms of "white" since our white is the paper. But recently working in oils, titanium white suddenly becomes a new variable I never fully-appreciated. Not just it's tinting properties, but the effect it's high opacity has on the palette-blends.

Re: Colour shift when mixing with titanium white

I could not speculate on how useful the information may be to anyone, but I do enjoy seeing how the colors shift. Of the range of colors, many overlap in hue at certain values, while being different enough in mass to warrant their usage individually quite often (in the case of opaque colors of high intensity).

Re: Colour shift when mixing with titanium white

Most pigments will shift towards somewhere in blue when mixed with titanium white. One just need to keep that in mind and add a bit of other color compensation .

I used to think too much abut it, but nowadays I think it is easier to just try stuff.. a lot of stuff.. you will in fact learn faster.
