Curves histogram only in B&W

[Adas50]

Hello,
I use Affinity Photo version 1.10.5.1342 when I open the Adjustments - Curves panel, the histogram appears in B&W even if the display is set to RGB (see attachment).

I can't figure out if it's a bug, if it's the fault of the computer I'm working on, if I've set the preferences wrong or more simply it's a feature of the program.

For more information I work on a Windows 11 platform with 16GB of ram.

In v1.10.5 on Mac, there appears to be a refresh bug. E.g. when I disable the RGB layers and there's only a grayscale layer left (or vice versa), the histogram doesn't update immediately. I need to click another layer first and then reopen the Curves window again.

Hi Ioukash,

I tried what you suggested in my case it doesn't work, I say more, not only does the histogram appear in B&W by selecting the RGB channel it is also the same with the LAB or CMYK channels

If it's a bug, then I'm afraid we're stuck with it in v1, as the only upcoming updates that were promised after the release of v2 so far were OS compatibility fixes…  
I haven't checked yet if it's been fixed in Affinity v2. I'd have to reboot my Mac from the Catalina partition first but currently I'm working in El Capitan.

Thank you i hope someone of the staff take charge of the issue.

I don't think it ever was in colour, (are you thinking of the Histogram tab,) or is this a feature request?

Hi PaulEC,
I've always seen it in B&W on my computer, but I've seen the program work on a Mac where the histogram appears in color, hence my post.

Seeing the color histogram makes it easier to read the color cast in the lights and shadows, it's been a while since I've used Photoshop but if I remember correctly the histograms were in color.

I could also propose it as a feature but I think with the advent of version 2 nobody would consider it.

Thanks for the reply, at least I know it's not a PC or preference issue

I think you're right about Photoshop!

I'm running Catalina on my Mac, & with this there is no refresh issue that I can see -- it just takes a second or two for the window to update.

Also, not of any help to the OP but in both V1 & V2 in my Mac, the curves are B&W only for the Gray & LAB settings.

Hey @Adas50 apologies for the late reply,

The Histogram on the Curves adjustment showing B&W on Windows has been resolved in V2, the chances of this being retrospectively fixed in V1 is unlikely, unfortunately.
