Is LCH chroma working correctly?
Due to lack of documentation, It is extremely hard to tell what each of the LCH blending modes do...
However, It seems like LCH color and LCH chroma are doing the same thing (Tested on 6 different images, RGB, 8 bits per channel.
More than than... I am not sure if LCH chroma is working correctly, as it actually shows greyscale pixels as non-black (depends on the hue)... I would figure that they should be black, So what exactly am i looking at? (No need for images, you can try it yourself)
1.)Have two layers with transparent background, first layer - raw black (0x00) in value (LCH chrome mode) (Should be the first layer on top) (Toggle visibility off)
2.)The other one, any image you wish (Normal mode) (Or a blank one) (Should be visible, BELOW LCH chroma layer in a layer group)
3.)Put pure white pixel (0xffffff) anywhere in the second layer, the normal mode one.
4.)toggle LCH chrome visibility layer on
5.)See if the pixel is white or black.
(To me, its white while i expected it to be black)
