hi! i have this scenario: i have a column in my postgis table which contains a double representing a percentage.
i want to color my polygons in a gradient fashion based on that number. the docs states three ways to specify color: 1. three [1-255] numbers 2. hex string 3. [attribute] but the attribute must be a string by itself in the same format as options 1 or 2. how can i achieve something like COLOR [percentage]*255 0 0 or COLOR [percentage] 0 0 if percentageis already 0..255 for a red gradient for example? thanks allot!
