... There was an awful rainbow once in heaven:
We know her woof, her texture; she is given
In the dull catalogue of common things.
Philosophy will clip an Angel’s wings,
Conquer all mysteries by rule and line,
Empty the haunted air, and gnomed mine —
Unweave a rainbow…

… we identify a single nucleotide substitution in an anthocyanin-activating R2R3-MYB gene causing flower color variation between a pair of closely related monkeyflower (Mimulus) species, the hummingbird-pollinated Mimulus cardinalis, and self-pollinated Mimulus parishii. This causal mutation is located in the 5′ untranslated region and generates an upstream ATG start codon, leading to attenuated protein translation and reduced flower coloration in the self-pollinated species.
