<Confusion about applying hue to a grey value>
Try this:
>>> import colorsys as cs
>>> grey = (.7, .7, .7)
>>> blue = (0., 0., 1.)
>>> hsv_grey = cs.rgb_to_hsv(*grey)
>>> hsv_blue = cs.rgb_to_hsv(*blue)
>>> hsv_grey
(0.0, 0.0, 0.69999999999999996)
>>> hsv_blue
(0.66666666666666663, 1.0, 1.0)
The problem is that the saturation of the grey is 0. There
is no Hue to anything between black and white. Maybe you want
something like:
def apply_hue(color, rgb):
hue, _saturation, _value = cs.rgb_to_hsv(*color)
_hue, saturation, value = cs.rgb_to_hsv(*rgb)
return cs.hsv_to_rgb(hue, max(.1, saturation), value)
Or:
def apply_hs(color, rgb):
hue, saturation, value = cs.rgb_to_hsv(*color)
_hue, _saturation, value = cs.rgb_to_hsv(*rgb)
return cs.hsv_to_rgb(hue, saturation, value)
