Hey, ChatGPT, Give me a brief explanation of how humans perceive colour and how it affects our mood.

Human perception of colour is a complex process involving both physiological and psychological factors. The process begins with light entering the eye and stimulating specialized cells called cones in the retina. These cones are sensitive to different wavelengths of light, which correspond to different colours.
There are three types of cones, each sensitive to either short (blue), medium (green), or long (red) wavelengths of light. The brain then processes the signals from these cones to create the perception of colour. Additionally, there are also rods in the retina that are more sensitive to low light levels and do not perceive colour.
Colour perception can have a significant impact on mood and emotions. Different colours are associated with various psychological effects:

1. Red: Often associated with energy, passion, and excitement. It can also evoke feelings of danger or aggression.
2. Blue: Known for its calming and tranquil qualities. Blue is often associated with stability, trust, and serenity.
3. Green: Linked with nature, growth, and harmony. It can promote feelings of balance and renewal.
4. Yellow: Typically associated with happiness, optimism, and warmth. However, it can also be overwhelming in large doses.
5. Orange: Combines the energy of red with the cheerfulness of yellow. It can evoke feelings of enthusiasm and vitality.
6. Purple: Associated with luxury, creativity, and spirituality. It often evokes a sense of mystery and sophistication.
7. White: Symbolizes purity, innocence, and cleanliness. It can also create a sense of spaciousness and simplicity.
8. Black: Represents power, elegance, and authority. It can also be associated with mystery or negativity.

These associations are not universal and can vary depending on cultural and personal experiences. However, colour psychology is widely used in marketing, interior design, and art therapy to influence mood, behavior, and perceptions.

As a professional product photographer here in Peterborough, I think about colours every single time I am given a project. These definitions and descriptions are so important to everything I do, none can be taken for granted. My studio here in Peterborough where I shoot products for businesses of various types, is a colour calibrated studio.  My cameras are calibrated, as is my computer monitor.
The lights I use are all near to the same colour balance to assure that my customers get the best quality that I can achieve.
Every month I recalibrate my equipment and double check my workflow. I'm constantly updating my skills in post-production to make sure I have a thorough understanding of what's achievable in the current software. These things matter.
I care about the results, so it matters that I pay attention to all the relevant details that could potentially affect the results of my efforts.
