The Color Key window lets you isolate a range of colours in the input signal. Pixels outside the selected range are displayed as black in the Source Signal viewer, making it easy to spot specific tones or check colour separation.
Open it from the menu bar (Options > HSV/RGB Key) or assign the Toggle HSV Key window action to a StreamDeck button or keyboard shortcut.
HSV Mode
Narrow the selection by Hue (0–360°), Saturation (0–100 %), and Luminosity (0–100 %). Each channel has a visual range slider with a colour gradient — drag the handles to define the start and end values.

RGB Mode
Select a range for each Red, Green, and Blue channel independently (0–100 %). Useful for isolating specific signal levels per channel.
