Red is for me a primary choice of color. It reminds me to be careful and attentive
Red is a neat color. Blue is my favorite because I like the sky.
What I like about red is that it has dominant wavelength. Blue mainly indicates calmness and rest
What is a dominant wavelength?
In color science, it is the physical property that defines the intensity of light beaming to create that specific color that we see
I understand what wavelength is. I just don't know how determine which one is dominant.
They are measured in nanometers. Usually calculating the frequency of wave repetitions. High frequency means high intensity, thus dominance
