I think I understand what @SooniX wants and needs:
The Specific Colour Selector works with RGB values.
To specify the colour in terms of HSV values, you need the Choose A Colour window. This is not a docker:
I can never remember how to get this easily and I do it by clicking on one of the small coloured squares at the bottom of the Digital Colours Mixer docker.
I hope @EyeOdin or someone knows a more convenient way to get it on-screen.
In that window, you can specify the colour in HSV form but you’ll notice that the S and V values are percentages, not 0-255.
So, with 227, 150, 63 from the colour selector on the other application, you’d have to convert those numbers to percentages, 150/255 and 63/255.
This gets the result shown in the image above and it doesn’t have exactly the same hex code that EyeOdin gave 
Edit:Add: That doesn’t actually change the selected colour. I’ve no idea what’s happening there and I think it’s related to the use of the Digital Colour Mixer docker.
