The pattern of light absorbed by a compound is known as its absorption spectrum. When binding oxygen, haemoglobin absorbs light in the blue-green and yellow parts of the spectrum, but reflects back red light, and this is the reason why we perceive arterial blood as a vivid red colour. The absorption spectrum changes when oxygen dissociates from haemoglobin in venous blood. Deoxyhaemoglobin absorbs light across the green part of the spectrum, and reflects back red and blue light. This gives venous blood its purple colour.”” [Nick Lane](https://sms4smile.com/quotes/author/nick-lane/) ## About This Quote This interpretation was drafted with AI assistance.
