What would be the preferred way to convert opacity (0 – 1) to hex (00 – ff) in Javascript?
My thoughts are to use an if statement to check if opacity is between 1 and 0.95 then use ff. Work my way down to 0.

The 0.0 – 1.0 range is just a percentage format of the 0-255 range. So multiply your value (e.g. 0.5 * 255) then convert to hex, you’ll get the correct value.
