hue_isolation

type: "hue_isolation"

Keeps the chosen hue, everything else goes grayscale.

Fields

Every screen effect also accepts screen_layer and the shared definition fields (duration, easing, loop, persistent, fade_ticks, sound).

Field	Type	Default	Meaning
hue	float	0	Target hue on the colour wheel: 0 = red, 0.33 = green, 0.66 = blue, 0.5 = cyan/magenta boundary... (full circle 0..1)
tolerance	float	0.2	Hue match width: how far from hue (on the 0..1 wheel) a pixel may be and still keep its colour
intensity	float	1 (fades to 0)	Strength of the grayscale conversion outside the tolerance

    "params": { "hue": 0, "tolerance": 0.2, "intensity": 1 }
}
