Firstly you need to apply brands colors and elements and find shades that are good for screens (use RGB color codes). Make sure, also, to use appropriate text sizes ( eg. 14 pt for body text).

To make color choices accessible in digital graphics, use high-contrast color combinations that meet WCAG standards, ensuring readability for users with visual impairments. Check color contrast ratios, aiming for a minimum of 4.5:1 for text and 3:1 for larger elements. Avoid relying on color alone to convey information; instead, add labels, patterns, or icons to support clarity. Test your design in grayscale and with color blindness simulators to confirm accessibility for all users, creating inclusive graphics that everyone can enjoy.

I first make sure to use a color contrast checker tool to verify that the contrast between foreground and background elements meets accessibility standards, such as WCAG 2.1, aiming for a minimum contrast ratio of 4.5:1 for text. I also employ a color blindness simulator to check how my graphics appear to individuals with different types of color vision deficiencies. To enhance accessibility further, I rely on more than just color to convey information, using patterns or text labels where possible. Finally, I seek feedback from individuals with diverse visual abilities to refine my designs, ensuring a broader, accessible appeal.

I ensure color accessibility by using high-contrast color schemes, checking readability with color-blind simulators, and testing against WCAG standards. This approach helps all users, including those with visual impairments, to comfortably access content.
