Examples

From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.

lab  = text(120, 5.35, "6 dB = 1 bit", color = "#0E7C86")
rule = hline(6, dash = true, width = 1.4)
rule.color = lab.color        # one ink, stated once

print(rule.color)             # "#0e7c86" -- the rule really did pick up the label's colour

output

#0e7c86
