Changing / replacing a color
I am trying to change a red rose into a yellow rose using the CO color editor. Does anybody have a suggestion where I can find a workflow tutorial on changing colors. I can make the color change in CS6 or Affinity Photo, but I'd prefer to do it in CO.

There are tutorials or you could do this.
(1) Create a layer (so that you can change the red in the rose without affecting the red in anything else). Draw a mask over the rose. It need not be too precise as long as it covers all the red and doesn't include any other red objects.
(2) Go to the colour editor advanced tab. Choose the picker tool and click on a red part of the rose.
(3) Drag the hue slider all the way to the right (+30). That moves you 30 degrees anticlockwise round the circle.
(4) If that has changed the colour as you want it to, well and good. If it's gone too far towards the green, pull the hue slider back to the left a bit.
(5) I it hasn't gone far enough, you can just do it again. (You can only go a maximum of 30 degrees at a time.) Click on the same part of the rose and pull the slider towards the right again.
(6) If you find that some parts of the rose get changed and some don't, or that more get changed than you wanted, try dragging around the boundaries of the "pie slice" to make it narrower or wider, or to pull it further out to the edge of the pie, or drag it in from the edges a bit.
Meanwhile I'll try to find the relevant YouTube video and post a link.

Ian3, Thank you!!! 0 -
Ian,
Much thanks.
Everything worked as you described.
Once I got close to my end goal color, I then adjusted the saturation and lightness sliders to achieve the exact shade that I wanted.
Since my wife and daughter delight in making fun of my "typical male color insensitivity", is there a way to "dial in a desired RGB value", eg R=255, B=0, G=0?0 -

This functionality doesn't exist within Capture One, though I do suggest submitting the feature request formally, via the link in my sig0 -

Well, sort of.
You can set those values per colour with the levels tool.
So if you selected a mask based on the red rose's colour *as before) and applied that to a layer (has to be a layer anyway of course) an then set the Red to 255 for both values at the top of the tool and Blue and Green to to 0 for both values at the top of the tool you would have a pure red under anything you masked.
You might want things top be a bit more subtle than that but you could start at that point and then tweak things as required.

Hello
I have exactly the same question but for me it does not work ☹️
I created a thread about it a bit before. I have a model on a white background . I wanted to turn the backgourng into light green. It did not work. I was explained that in itself white is not color. That I can understand.
So I found a photo of the model where the background is blue (not blue blue but in a range of blue). So I created a layer by first drawing with brush a mask on the model. Then a second layer by copying and inverting the previous mask.
Now I start to work on color editor with this mask. I change hue value slightly . then create another layer to go smoothly to my target value, the mask remains the same. At each step, I control in the view color selection that my model is not affected. She was always in B&W but at one point (meaning a new layer) when I push the control box in view color selection, she turns red. meaning that the change begins global ???
What do I miss in editing and replacing a color in a layer ??
thanks for help0 -
So (forgive me for asking something that is probably unnecessary) but after creating your mask for the blue background did you use the picker tool to select that range in the colour wheel? And are you using the basic or advanced colour editor?
Ian
Edited to also ask whether you had the "show selected colour range" option checked? You can use that to check that you have selected the right parts of the image, but after doing so, turn the check box off again.0 -
Here is an example.

I've (1) created a layer and (2) drawn a gradient to mask just the top strip of the blue sky. Then I (3) used the colour picker to select the blue colour and (4) pulled the hue slider as far as possible to the right to 30. The (5) clicked again on approximately the same point in the picture and pulled the new hue slider to the right again. A total of 4 goes got me round from blue to red.
Can you try something like that on an image that has a very obvious colour just to check that it works? You can create a new variant of your image before you start so that you can experiment as you like without wrecking anything.
Ian
Edited to add: that red band at the top of the image is the changed sky colour, and not just the mask.0 -
Thanks Ian
by re-reading the post and the tutorial , I managed gradually by putting the hue value - 30 to achieve my color. I did that in the same layer as you have shown it. not creating new layers each time 😊 Thanks a lot !!!
It is not to bother you but now I would like to do the opposite. I have a part of my image which is too grayish and I would like to turn back closer to white. I created a layer and then a mask on this area and I try to play either with the white balance or the advanced color editor locally ?
Another question in C11, it is not possible like in lightroom to affect to highlights or shadows in HDR part with negative values ?
Many thanks for your help an patience.
ps: I have still this strange effect that I work within the mask of the layer in the color editor and at some point in view selected colors box I see that other part of the image turning to red. It creates a panic, I close C11 and open it again then I see gladly that nothing has been modified outside.0 -

If part of the image is too grey, and you want it to be whiter, then the solution is to do with brightness, exposure or contrast isn't it? You could mask the area in question and then apply locally either an exposure increase, or a brightness increase, or a contrast increase, or apply a curve adjustment just to that area, or a levels adjustment (pulling in the right hand slider).
