I was doing some research, and I have read somewhere on the internet that is not recommended to use homogeneous range of values for color progression between classes (eg., 20%, 40% 60% 80%, 100%) when we are using "value" as visual variable in cartography.
Than, I assumed there might be some "rules" to define a good color progression!
For example: "Black 0, Black 10, Black 30, Black 60 and Black 100" which corresponds to a variation of 10% between the second and first class, 20% between the third and second class, 30% between the fourth and third class and 40% between the fifth and fourth class.
I would like to kindly receive your opinion/feedback about this topic.
Thank you in advanced..
Dear Patrik Silva, it depends mostly on your specofic task and your aesthetic sensitivity. Feel free to use your own color scheme that most suitable to your goal. For example, use contrast colours if you need to unveil some thresholds, etc.
