megapleb Posted July 19, 2022 Share Posted July 19, 2022 (edited) Hi, I'm sure this is a problem with my understanding, but I've never seen a photo editor do this before, and despite googling, I can't find a solution. When opening many images, on the colour panel, instead of instead of the usual RGB slider colour ranges (black to red, green and blue), the ranges are cyan, magenta and yellow to white. Did a default change in an update, or did I accidentally change a setting? I'm used to working entirely in RGB and would like to get back to that colour space. This is what it looks like now - https://imgur.com/a/4hg8OU8 Edited July 19, 2022 by megapleb attached screenshot Quote Link to comment Share on other sites More sharing options...
GarryP Posted July 19, 2022 Share Posted July 19, 2022 Welcome to the forums @megapleb The screen-grab in your link shows RGB sliders so I can’t see what the problem is. Note: It’s generally best to give us full-screen screenshots (they give us much more information) and attach them directly to your post rather than adding a link to another site (which some users may not want to go to, for whatever reasons).

megapleb Posted July 19, 2022 Author Share Posted July 19, 2022 (edited) Hi, Thanks for the response. The problem is the range on the sliders. Instead of being black to red, black to green and black to blue, as they always used to be, they are now CMY to white.

Dan C Posted July 19, 2022 Share Posted July 19, 2022 Hi @megapleb, Welcome to the Affinity Forums This would indicate your document colour format is currently CMYK - which may have been set automatically depending on the image you opened in Affinity. To change the document colour format, please navigate to Document > Convert Format / ICC Profile, then in the dialog that opens change the Format to RGB/8 and the Profile to sRGB IEC61966-2.1 and click Convert. You should find the colour sliders are now displayed as expected! See: Quote Link to comment Share on other sites More sharing options...
GarryP Posted July 19, 2022 Share Posted July 19, 2022 As I said in my previous post, I’m seeing the normal RGB sliders, and the same in your latest post (thanks for attaching it), so I can’t see what the problem is. I’ve attached two screen-grabs, the first is RGB sliders, the second is CMYK sliders. Quote Link to comment Share on other sites More sharing options...
megapleb Posted July 19, 2022 Author Share Posted July 19, 2022 Hi Dan. I did as you suggested, and the sliders remain with CMY ranges. Also, when I create a new image in Photo, they have CMY ranges. I've attached my colour preferences. Quote Link to comment Share on other sites More sharing options...

Sorry if I am confusing my terms, but I believe my desired result is clear. Quote Link to comment Share on other sites More sharing options...
Dan C Posted July 19, 2022 Share Posted July 19, 2022 Thanks for the further screenshot - this may be due to your colour profile / monitor profile in use, as I suggested above, what happens if you use the default sRGB IEC61966-2.1 profile in your document?

GarryP Posted July 19, 2022 Share Posted July 19, 2022 Your original example showed RGB sliders, your next example showed RGB sliders, your full-screen screenshot showed RGB sliders. As far as I can tell you are seeing RGB sliders but calling them CMYK sliders for some reason. Quote Link to comment Share on other sites More sharing options...
Dan C Posted July 19, 2022 Share Posted July 19, 2022 @GarryP The sliders themselves are as expected, its the colours shown behind each slider that the user is trying to change. In a default RGB document, the colours shown in the sliders are Black > Red, Black > Green & Black > Blue, respectively. In a CMYK document (or with certain colour profiles) these sliders instead display as Cyan > White, Magenta > White & Yellow > White, respectively. The sliders will still perform the same actions, but the user prefers the visual representation of Black > RGB, respectively. Quote Link to comment Share on other sites More sharing options...

Nothing changes. I also changed the preferences to sRGB IEC61966-2.1 for RGB, closed the app, reopened, and created a new file. The colour ranges on the sliders remain as before. I have no recollection of changing any of the colour settings before I encountered this problem today. Quote Link to comment Share on other sites More sharing options...

Why is the R slider showing a Cyan color, the G showing a Magenta color, etc.? That is the question.

Dan C Posted July 19, 2022 Share Posted July 19, 2022 Thank you for trying that and I'm sorry to hear that hasn't helped! Can you please open Windows Run (Windows Key + R) then paste the following and press OK: colorcpl In the dialog that opens, make sure your primary monitor is selected in the dropdown list, then provide a screenshot of this for me here?

megapleb Posted July 19, 2022 Author Share Posted July 19, 2022 I went through the calibration process to create a colour profile for my monitor. Here's what it looks like now. Unfortunately, it didn't change anything with Photo. Quote Link to comment Share on other sites More sharing options...

Because the color/gradient on the slider does not show the intensity of the color component (it would always be the same, and can be easily imagined from the position of the slider, or from the given numerical value), but the color to which the selected color changes after moving the slider to the given position.

megapleb Posted July 19, 2022 Author Share Posted July 19, 2022 Up until today, if I moved the G slider to 255, the colour ranges shown on R and B would have remained black to red, and black to blue respectively. It seems to have changed from absolute colour values, to showing the range relative to the colour currently selected. I can see how this makes sense, and could be useful, but it's not how I'm used to working. Quote Link to comment Share on other sites More sharing options...

Not to worry Garry, I'm blaming the heat in the UK today - as clearly I'm not thinking straight either as there's no bug here! @megapleb the reason the colours change in these sliders is due to your currently selected colour - with White selected the RGB sliders will display in Cyan, Magenta & Yellow, with Black selected you will see Red, Green & Blue. This is simply how the colour sliders change with the currently selected fill, to show how your colour will change when increasing each slider. For example, with White selected, moving the R slider towards the Cyan colour in the slider will give you a Cyan coloured fill, as you now have 0,255,255 selected.

Did I just imagine for the last year that the sliders worked in an absolute manner with fixed ranges within Photo (as I'm used to them doing in Photoshop) rather than relative ranges based on the currently selected colour? Is there any way to get the sliders to operate in a fixed range (black to R, B, G)? Edit - I understand it's more useful this way, as you can see how moving each slider will change the colour. What I'm asking for will provide less information. I just want to check I'm not crazy. There's no way I didn't notice this for the last year.
