Instead of only working with a handful of colors, you can create a whole palette of swatches at the same time so you can see if they look good together. Precise control of every shades/tints in each swatch rather than being limited by autogenerated colors. See which color pairs contrast as you edit so you can create a palette with built-in WCAG accessibility.
Per The WebAIM Million report, low contrast text represents 79.1% of all errors on the 1M homepages they analyzed via automated testing. People with low vision often struggle with text that blends into its background, especially if they also have a color vision deficiency. And as people like you and me age, this becomes especially important. Ensuring a minimum contrast ratio between text and background makes it easier to read, even for those who see limited or no color.
