I don't need anything. You need to read. The plugin does what you want if you look at the settings.
# C4 timer color mode.
# The settings in brackets for each mode will be active only when that mode is selected.
# 0 = use one color only [STARTING_COLOR]
# 1 = use color cycle [STARTING_COLOR + COLOR_CYCLE]
# 2 = use a random color each second
COLOR_MODE = 1
