+# "kohlrausch" colour theme for mintty

+#
+# This is a variant of the "helmholtz" theme that has been designed for use
+# with a dark text colour and light background, by darkening the foreground
+# variants of the normal colours and brightening the background ones.
+#
+# To level the colours, their luminance was calculated as follows:
+# - Gamma-expand the sRGB components by dividing each by 255 and applying the
+#   sRGB transfer function (which approximately means applying exponent 2.2).
+# - Combine the components with formula Y = 0.2126 R + 0.7152 G + 0.0722 B.
+# - Gamma-compress with the reverse transfer function (approximately: apply
+#   exponent 1/2.2).
+#
+# https://en.wikipedia.org/wiki/SRGB
+#
+# The colours were then adjusted to achieve equal luminance. However, that does
+# not actually yield colours with equal apparent brightness. This is due to the
+# "Helmholtz-Kohlrausch effect", which means that some saturated colours appear
+# brighter than others to the human eye. The theme is named after that.
+#
+# https://en.wikipedia.org/wiki/Helmholtz-Kohlrausch_effect
+#
+# There doesn't appear to be a generally valid model for compensating for the
+# effect, as it depends on observer, display device, and viewing environment.
+# Hence, correction factors were determined experimentally, ranging from 1.0
+# for yellow to 1.45 for red, and the colour components adjusted accordingly.
+# Of course, that is a highly subjective process ...
