WCAG Contrast Guidelines

Level	Normal Text	Large Text
AA	4.5:1	3:1
AAA	7:1	4.5:1

Large text = 18pt+ or 14pt+ bold

# Check if colors meet WCAG AA
if vg.meets_wcag(text_color, bg_color, "AA"):
    print("Accessible!")

# Automatically fix contrast
accessible_color = vg.ensure_contrast(text_color, bg_color, min_ratio=4.5)
