color ramp
Maps an input float through a color gradient and outputs an RGB color. The input value is first remapped from the [In Min .. In Max] range to [0..1], then sampled along the gradient to produce the output color. Useful for colorizing scalar particle attributes such as age, speed, temperature, density, or any value-driven channel.
Edit the gradient inline on the node: click the bar to add a knot, double-click a knot to pick its color, drag knots to reposition. Right-click for interpolation type, presets, and copy/paste.

[Inputs]
#Value - Input float to sample the gradient with. Values outside the [In Min .. In Max] range are clamped to the nearest endpoint..
In Min - Input minimum range. Values at or below this map to the left edge of the gradient (position 0).
In Max - Input maximum range. Values at or above this map to the right edge of the gradient (position 1).
[Outputs]
Color - Resulting RGB color sampled from the gradient at the remapped position.
