Your developer says the design system uses colors in HSL. Your design tool shows colors in HEX. You need to convert. You use a color converter. You enter the HEX value #4A90D9. The tool shows the RGB (74, 144, 217) and the HSL (212, 64%, 57%). The developer gets the format they need. The color converter is a conversion tool. It translates colors between formats.

Now you are choosing text colors for a website. You want light gray text on a white background. It looks stylish. But can everyone read it? You use a color contrast checker. The tool computes the contrast ratio between the text color and the background. The ratio is 1.9:1 — well below the WCAG AA requirement of 4.5:1 for normal text. The light gray text is unreadable for many users. You darken it. The color contrast checker is an accessibility tool. It tests whether colors are readable.

Both are color tools. Both are essential for designers. But the tasks differ. The color converter is for format matching — translating colors between HEX, RGB, and HSL so teams communicate. The color contrast checker is for accessibility testing — verifying that text is readable by all users. The CSS minifier optimizes the final stylesheets. The color converter handles the format. The contrast checker handles the compliance. Different tasks. Both essential.
