Question 1

What does the Colours tool do?

Accepted Answer

It is a browser-based colour explorer and converter. Input a colour in HEX, RGB, HSL, or HSB and instantly see conversions to all other formats, plus complementary colours, shades, tints, and a full palette preview.

Question 2

What colour formats are supported?

Accepted Answer

HEX (#RRGGBB), RGB, HSL, HSB/HSV, and CSS colour names. You can convert between any of them instantly.

Question 3

Can I generate a colour palette?

Accepted Answer

Yes. Generate complementary, analogous, triadic, and monochromatic palettes from any base colour — useful for web design, branding, or data visualisation.

Question 4

Can I copy values for CSS or Tailwind?

Accepted Answer

Yes. Click any colour value to copy it in a CSS-ready format.

Question 5

Can I link directly to a colour?

Accepted Answer

Yes. The converter reads URL parameters and keeps the address bar in sync, so you (or an AI assistant) can build a deep link by hand. Open ?hex=1a2b3c to load the converter showing HEX, RGB, HSL and the closest CSS name. The value works with or without the # and also accepts rgb() or hsl() strings (aliases color, colour, c). Use ?search=blue to filter the named-colour grid instead.

Question 6

What color is this? How do I find a color's name?

Accepted Answer

Paste a HEX, RGB or HSL value into the converter and it instantly returns the closest CSS color name. It works as a color identifier and color namer in one: give it a value, get the name.

Question 7

How do I convert a HEX code to a color name?

Accepted Answer

Type or paste the hex (for example #1a2b3c). The tool finds the nearest named colour from the 140+ CSS colors and shows it with RGB, HSL and HSB. The hex-to-color-name lookup also works from a shareable link — open ?hex=1a2b3c to jump straight to the result.

Question 8

Can I convert RGB or HSL to a color name?

Accepted Answer

Yes. Paste an rgb(...) or hsl(...) string and the converter returns the closest color name plus every other format. RGB-to-color-name and HSL-to-color-name use the same nearest-match logic as the hex lookup.

Question 9

Is this an HTML / CSS color finder?

Accepted Answer

Yes. It is an HTML color finder and CSS color-code finder: browse all 140+ named web colors, search by name or hue, and copy a CSS-ready color or background value in one click. Every named colour shows its hex, RGB and HSL.

Question 10

How many named colors are there?

Accepted Answer

There are 140+ standard CSS / HTML named colors, from aliceblue to yellowgreen, all searchable here. The nearest-name lookup maps any of the 16.7 million possible hex values back to the closest one of these names.

Question 11

Can I copy a color name with its hex code?

Accepted Answer

Yes. Click a colour to copy its name, hex, RGB or HSL to the clipboard, ready to paste into CSS, a design tool, or a document.

Question 12

What is the difference between HEX, RGB, HSL and HSB?

Accepted Answer

HEX and RGB describe a colour by its red, green and blue channels — hex just writes them in base-16. HSL (hue, saturation, lightness) and HSB/HSV (hue, saturation, brightness) describe the same colour by how we perceive it, which is easier for picking tints and shades. This tool shows all four at once.

Question 13

Does it work on mobile, and is my data private?

Accepted Answer

Yes. The finder runs entirely in your browser on phone, tablet or desktop. Nothing is uploaded and no colours are stored on a server. It works offline once loaded.

Question 14

Is this tool free?

Accepted Answer

Yes, completely free. It is one of many free tools at jasperbernaers.com.
