Raeli Colors

Scratchpad area for working out Raeli color progressions.

Hypotheses

• Convert color to HSV
• Hue = k1
• t = burn time / max burn time
• Saturation = t
• Value = 1.0 - k2 * t
• k1, k2 are determined by oven location and resin type?

To Do

Get timing data, and just more data in general (e.g. automate taking a screenshot every 10 seconds over the course of the entire run)

Color conversion

Horrible Python script to convert RGB to HSL and HSV colorspaces:

#!/usr/bin/env python
import sys
r = int(sys.argv[1])/255.0
g = int(sys.argv[2])/255.0
b = int(sys.argv[3])/255.0
minc = min(r,g,b)
maxc = max(r,g,b)
if maxc == minc: h = 0
elif maxc == r: h = (60 * (g-b)/(maxc-minc) + 360) % 360
elif maxc == g: h = (60 * (b-r)/(maxc-minc) + 120)
elif maxc == b: h = (60 * (r-g)/(maxc-minc) + 240)
l = (maxc-minc) / 2.0
if maxc == minc: hsl_s = 0.0
elif l <= 0.5: hsl_s = (maxc-minc) / (maxc+minc)
else: hsl_s = (maxc-minc) / (2 - (maxc+minc))
if maxc == 0: hsv_s = 0.0
else: hsv_s = (maxc-minc) / maxc
v = maxc
print "Raw: %5d %5d %5d" % (int(sys.argv[1]), int(sys.argv[2]), int(sys.argv[3]))
print "RGB: %5.3f %5.3f %5.3f" % (r,g,b)
print "HSL: %5.1f %5.3f %5.3f" % (h,hsl_s,l)
print "HSV: %5.1f %5.3f %5.3f" % (h,hsv_s,v)
