v2.4.1 - Backgrounding2 - RGB fix; rgb processing is now fixed on 255-based numbers which are converted internally to percentage-based numbers; there is currently no way to pass percentage-based RGB directly; should implement color-hsb param to use with RGB; edited help and readme to say we need 255-based numbers for RGB. CMYK mode is preferred over any other.
