What are the best colors to use on a bar graph?
In terms of graphs and charts, you may choose to use gray for less-important variables and a deep red or orange for the most crucial variable, for example. Alternatively, you could use muted colors for the less-important options and a bright color for the most important ones.
What colors should not be in charts?
It is confusing and distracting. Also, don't use red and green or orange and green to make comparisons on the same chart. About 10% of men are color blind with red/green being the most common form of color blindness. Orange is close to red, making these colors completely indiscernible.
How to pick more beautiful colors for your data visualization?
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. Choose colors with different saturation values to make sure users can differentiate between colors regardless of their hue.
