As far as I know, it uses the normal HSL calculation, but I have not verified this in detail.

Can you give an example?

Base Layer (bottom layer)
r1 = 255;
g1 = 123;
b1 = 65;
Blend Layer(top layer)
r2 = 45;
g2 = 255;
b2 = 200;

Usually the Color Blend mode (H2, S2, L1) gives you RGB(65, 255, 207), but Photoshop gives you something like (14, 225, 170);

[re color blend mode]

Yes, and this is not the case. Although I can confirm the behavior, I can’t explain it at the moment. Perhaps someone else will chime in.

In Lab mode, the Lightness, a, and b channels are combined as you would expect (L1, A2, B2), but not in RGB mode, where the lightness and saturation values are not what I would have predicted.
