toggle to greyscale like in rebelle 3

[Victor]

in rebelle 3 pressing g will toggle the canvas to greyscale and back, this kind of ability will help the artrage users tremendously . i also think there is no way to change the canvas to greyscale and back to quick check the values in artrage.

If you find you need to check values often, you can place a layer filled with pure black at the top of the Layers stack and set it’s blend mode to ‘Colour’, You can then toggle this layer’s visibility On/Off to check the painting’s values.

Thanks for that helpful tip, still a hotkey would be nice in the future.
