I stand corrected, I did some tests in that color wheel, I don't know why I didn't try a color wheel myself in the first place, but yeah it seems that the grayscale algorithm in pureref is slightly different compared to the black layer on color blend mode. Now the question is, is this black layer with color blend the right algorithm? I'm not sure, both ITU-R BT.709 and ITU-R BT.601
I'm not a dev, I'm just a guy that looked into this. PureRef already uses an equation similar/compatible with the black color layer. If you search the forum it has already been talked about a couple of times, including myself. The conversion to grayscale is ITU-R BT.709, Luminosity as you say. As far as I can tell PureRef does that already, it's the only option and it's the cor
Hello dear developers. I'm amazed by the day with PureRef and I'm sure I'm just scratching the surface.
I have a simple suggestion which I think it will be a great addition: include a color wheel of some sorts or color rectangle or something that gives more than the color and the color code in the LMB+S color picker. This would be great because most times you want to visually see
I did test with pure reds & blues and other colors, I just didn't include it in the pic here. Now that you mention it I see there's a very slight difference. But really it's so minimal from the practical point of view I'm ok with it. Not to say that I'm against more tests and possibly fixing it if there's a problem.
I was also looking into this to see if it's correct (that is if it takes in account color inherent value as well) and I'm happy to see that it does. https://imgur.com/a/9V6hq. Images on the left are desaturated by pureref and ones on right are desaturated in Krita and pasted in pureref for conveneince.
I compared it with Krita's Desaturate Luminosity (ITU-R BT.601) algorithm whic
Was searching for duplicates of what I want to suggest and found this feature which I didn't know about :). But I have a suggestion - improvement: add a `copy` button that will copy the hex value (including # sign?!), would be much easier than `S+click` -> `select` -> `ctrl+c` -> `ctrl+v` :)
