Usage: col_util [options] various plots of maps, colors and blendings Options -h,--help this help message (run 'off_util -H help' for general help) --version version information -o <file> write output to file (default: write to standard output) -f <type> for output type 4, map is output instead of OFF file map type: rgb=1, antiprism=2, decimal=3 (default: 1) Scene Options -M <mode> color system mode. HSV=1, HSL=2, RGB=3 (default: 3) plot as cone, bicone or cube respectively -d <int> output type. plot=1, wheel=2, grid=3, map=4 (default: 1) if color wheel and RGB, only one color blend is possible -V verbose output. show color blend RGBA components Output type 1 options -r <int> HSV/HSL chroma 0 - none (cylinder), 1 - conic, 2 - hexagonal -S HSV/HSL distribute colors heptagonally, 7 ways, as in the rainbow -k <int> container control (default: 2) 0 - suppress, 1 - no facets on chroma-2, 2 - full -z <int> 1 - show model upright, 2 - upright but don't rotate RGB cube -q <int> height of the HSL cones (default: no change) 1 - double, 2 - make 90 degree dihedral -p plot color centroid(s) Color Blending Options -s <sat> HSV/HSL saturation curve. Greather than 0 (default: 1) 1.0 - no curve. lower than 1.0 makes blends more pastel 4 numbers can be entered seperated by commas -t <val> HSV/HSL threshold to use average saturation (default: 1) between 0.0 (all averaging) and 1.0 (no averaging) -v <val> HSV/HSL value curve (default: 0) simulates subtractive coloring for blending 3 or more colors RGB: Red+Green+Blue = White Cyan+Magenta+Yellow = Black RYB: Red+Yellow+Blue = Black Green+Magenta+Orange = White 1.0 - no curve. lower than 1.0 number makes blends lighter 0.0 - use average value instead 4 numbers can be entered seperated by commas -u <val> HSV/HSL value advance. Rotates meaning of blend to white and black valid values 0.0 to 120.0 degrees (default: 0) -a <int> alpha for blend. average=1, minimum=2, maximum=3 (default: 3) -y RYB mode. Blend colors as in Red-Yellow-Blue color wheel -c CMY mode. Complementary colors. RGB->(RYB/GMO)->CMY->blend -b <val> All color sytem modes. brightness adjustment for final blend valid values -1.0 to +1.0 (default: 0) negative for darker, positive for lighter, 0 for no change Coloring Options (run 'off_util -H color' for help on color formats) -m <map> get colors from a color map, or multiple maps seperated by commas -O <file> get colors from an OFF file note: -m and -O may be used together -U allow only unique colors (sorts by color) -Z <int> maximum entries to read from open ended maps (default: 256)
