Chloroplasts and Color Anomaly

A color anomaly is the introduction of an outlier in an otherwise unified palette. A Fortuitous class demonstration of chlorophyll fluorescence came just hours after a lecture on color anomaly. I need little convincing to make artwork based on plant pigments.


Chlorophyll is green because it absorbs all visible wavelengths except green. Chlorophyll a specifically uses red and blue wavelengths in photosynthesis. These wavelengths have just the right energy level to be useful. Photosynthesis relies on excited electrons from which energy is harnessed. But excited electrons want to go back to their more stable, lower energy state. When the red wavelength drops energy levels it can fluoresce. This fluorescence can be demonstrated with a vial of extracted chlorophyll and a white light such as an LED.
