vector ocio_transform(string dest, vector clr)
vector ocio_transform(string src, string dest, vector clr)
vector ocio_transform(string src, string dest, string looks, vector clr)
Transform a three-component color into a new color space.
vector4 ocio_transform(string dest, vector4 clr)

src
The name of the color space to transform from. If this is not given, the function assumes the space assigned to "data".
dest
The name of the color space to transform to.
looks
A comma separated list of color gradings (also known as "looks").
clr
The color to transform.
