How do you choose colors for data visualizations Chartio?
Avoid having two colors with the same hue, but different lightness and saturation, unless the values associated with those colors are related. For example, you might have a line chart with daily readings in a light-colored line, and a weekly rolling average in a darker shade.
How do you choose colors for your data visualizations elaborate it with the suitable examples?
Avoid colors with low saturation and high luminosity. Unless your chart has a dark background, they won’t be easily visible. Remember that 1 in 10 men and 1 in 100 women are red-green color blind.

Which is the best colour scheme for data visualization?
Paul Tol provides a colour scheme optimised for colour differences (i.e., categorical or qualitative data) and colour-blind vision on his website, and in detail in a “technote” (PDF file) linked to there. He states: To make graphics with your scientific results as clear as possible, it is handy to have a palette of colours that are:

If you need to use colours though, I suggest you use a combination of high contrast colour values and limit them to two or three colours. For example in the figure below, I wanted to emphasize delayed activities for a Project.
