Another kind mix colours for gradients.

Another kind mix colours for gradients. i can show idea two gradients what are both made with Photo but right one is simulation (i cannot do it for all colours). these use different colour space calculate in beetween values. your current way i think use RGB values and other idea uses Hue Saturation Lightness values. i anyone what do graphics i bet like my idea and is i think also easy code. of cousress needs conver  colours to HSL space and back to original colour space but still.
and i have another tool what allows this but is palette based program and does not have vector shapes either.

Just choose HSL instead of RGB
