The best chart color scheme can vary depending on the context and the data being represented. However, some general tips for creating visually appealing and effective color schemes for charts include using high-contrast colors for readability, avoiding overly bright or neon shades that can be distracting, and considering colorblind accessibility. Tools like Adobe Color or Coolors can help in creating custom color palettes. For categorical data, using distinct hues is effective, while for continuous data, gradients or monochromatic schemes can be more suitable.
