This modules provides two functions for each color system ABC: rgb_to_abc(r, g, b) --> a, b, c abc_to_rgb(a, b, c) --> r, g, b All inputs and outputs are triples of floats in the range [0.0...1.0] (with the exception of I and Q, which covers a slightly larger range). Inputs outside the valid range may cause exceptions or invalid outputs. Supported color systems: RGB: Red, Green, Blue components YIQ: Luminance, Chrominance (used by composite video signals) HLS: Hue, Luminance, Saturation HSV: Hue, Saturation, Value t rgb_to_yiqt yiq_to_rgbt rgb_to_hlst hls_to_rgbt rgb_to_hsvt hsv_to_rgbg?g@g@g@cCs[d|d|d|}d|d|d|}d|d|d |}|||fS( Ng333333?gzG?g)\(?g333333?gQ?g{Gz?gzG?gp= ף?gףp= ?((trtgtbtytitq((s /usr/lib64/python2.7/colorsys.pyR%scCs|d|d|}|d|d|}|d|d|}|dkrWd}n|dkrld}n|dkrd}n|dkrd}n|dkrd}n|dkrd}n|||fS( NgD)X?gSh?gfb?g4Ry?gV?gvꭁ?gg?((R R R RRR((s /usr/lib64/python2.7/colorsys.pyR+s             c Cst|||}t|||}||d}||krKd|dfS|dkrl||||}n||d||}||||}||||}||||} ||kr| |} n+||krd|| } nd||} | dd} | ||fS(Ng@gg?g@g@g?(tmaxtmin( RRRtmaxctminctltstrctgctbcth((s /usr/lib64/python2.7/colorsys.pyRCs$      cCs|dkr|||fS|dkr6|d|}n||||}d||}t|||tt|||t|||tfS(Ngg?g?g@(t_vt ONE_THIRD(RRRtm2tm1((s /usr/lib64/python2.7/colorsys.pyRZs   cCsb|d}|tkr*||||dS|dkr:|S|tkr^|||t|dS|S(Ng?g@g?(t ONE_SIXTHt TWO_THIRD(RRthue((s /usr/lib64/python2.7/colorsys.pyRds    c Cst|||}t|||}|}||krCdd|fS|||}||||}||||}||||} ||kr| |} n+||krd|| } nd||} | dd} | ||fS(Ngg@g@g@g?(R R ( RRRRRtvRRRRR((s /usr/lib64/python2.7/colorsys.pyRts      cCs|dkr|||fSt|d}|d|}|d|}|d||}|d|d|}|d}|dkr|||fS|dkr|||fS|dkr|||fS|dkr|||fS|d kr|||fS|d kr |||fSdS( Ngg@g?iiiiiii(tint(RRRR tftpR tt((s /usr/lib64/python2.7/colorsys.pyRs(              N( t__doc__t__all__RRRRRRRRRR(((s /usr/lib64/python2.7/colorsys.pyts
