Design tools serve front-end and visual work: colour picking, palettes, CSS gradients, contrast checking and favicon generation. They show what you copy: the CSS updates as you drag a gradient. Colours come out in HEX, RGB and HSL, and the contrast checker returns a WCAG AA/AAA verdict.
A gradient, a palette or a site icon is a few lines of CSS or a small image. Generate locally, preview at once, then copy the code or download the file instead of round-tripping through design software. The contrast check also catches light-grey-on-white readability problems at development time.
How to choose the right Design
- Build palettes from one colour
Start from a brand colour and expand it into monochrome, analogous, complementary or triadic schemes. That is more coherent than picking five colours from scratch.
- Trust WCAG levels, not your eyes
WCAG asks for at least 4.5:1 on body text and 3:1 on large text. If the check fails, darken or lighten one side instead of judging by sight.
- Copy gradient code directly
The emitted CSS pastes straight into your stylesheet, and modern browsers need no vendor prefixes. The preview and the code always match.
- Generate favicons at every size
A tab wants 16 or 32 pixels while touch screens want larger ones. Generate the full set of PNG sizes in one pass so icons stay crisp everywhere.
Common design mistakes
- Contrast is about darkness
Contrast is a luminance ratio, not depth of colour. Two saturated hues can fall under 3:1 while two greys pass. Check ratios with a tool against WCAG.
- More colours, richer design
Past three or four main colours a page starts fighting itself. Start with one primary and one accent; extend only when justified.
- Gradient stops are arbitrary
Stop positions decide whether a blend flows. Evenly spaced stops often go muddy in the middle; stagger them or interpolate in OKLCH.
