Find me the good constrasts, for web accessibility, between these two colors:

Foreground Color : invalid color For each color (red, green and blue), enter a number between 0 et 255. The color should be between #000000 and #FFFFFF
Background Color : invalid color For each color (red, green and blue), enter a number between 0 et 255. The color should be between #000000 and #FFFFFF

In the international reglementation etablished by the WCAG, the success criteria 1.4.3 requires a minimum contrast ratio of 4.5:1 (and 3:1 for enlarged text).

This minimum contrast ratio is also required by the French regulation, established by the RGAA 3.0 2016, in the criteria 3.3 et 3.4.
