Select Visualization

Change the visualization of the layer

ramp($dn, [green, yellow, red])

Take colors from a color list. Since the input is an unclassified numeric property, interpolation of the colors values will be performed.
ramp($dn, temps)

Use the "temps" CARTOColors palette.
'ramp($dn, [hsv(0.5, 1,1), hsv(1, 1, 1)])'

Take colors from a color list with HSV color constructors.
'ramp($dn, [transparent, gray, yellow])'

The same as the first example, but showing that `ramp` supports transparency too.
