Use the format that matches the task
HEX is convenient for copying into design tools and CSS variables. RGB is useful when dealing with programmatic color values, and HSL is often easier when you want to think in terms of hue, saturation, and lightness changes.
Contrast belongs in the same workflow
Picking a pleasing color is not enough if text becomes unreadable on the chosen background. A useful color workflow checks conversion and contrast together so you do not ship a pretty but inaccessible combination.
Design systems benefit from consistency
Teams move faster when everyone can convert, compare, and document colors the same way. Even a small browser tool can save a surprising amount of friction in handoffs between design and implementation.
