This app (Application) allows you to evaluate the contrast between two colors,
sufficient or insufficient contrast for correct legibility or correct differentiation, for normal visual perception.
Calculation used: I get the distance between the hue of one color and the hue of the other color,
and I get the distance between the brightness of one color and the brightness of the other color,
and thus, I use those resulting values, to define the result of the evaluation for each one of the three relations taken.
Result that will be classified as Insufficient or Approved, as appropriate.
The result is based on the ratio taken, (7:1), (6:1), (5:1), are the ratios used.
It is recommended, to approve the contrast, to be based on the result of the evaluation that applies the ratio (7:1).
Each color can be edited by changing the amounts of red, green, blue, hue, saturation, and brightness. You can also choose color from a web color palette.
