Color Tools

Choose a colour, view the exact code and create an identical colour palette — and with no installation or downloads required, just in your browser. Choose any colour and get the value as soon as you pick it up, or convert between HEX and RGB if your design tool doesn't support your code. Or use the Colour Picker to create a full palette based on real colour theory, rather than taking a stab. Codes & combinations without any sign-up, without any install.

Why use OneShotSEO's Color Tools

  • Based upon one actual workflow, not a random collection of tools. Choose a color, discover all the forms it can take, and create a color palette based on it: the actual order a designer or developer would go in, not a random assemblage of similarly unrelated utilities.
  • Not a guess at colour theory, but real colour theory. The palette generator generates truly complementary, analogous, triadic, monochromatic and more colors in the way they relate, not random color palettes.
  • Copy all values at one. As soon as you generate or convert them, HEX and RGB codes are ready to copy. You don't need to do any extra clicks or have to reformate by hand; HEX and RGB codes are ready to copy upon generation or conversion.
  • No registration, no restrictions. Create palettes and/or conversions as many as you require, for as many projects as you have working.

How it works

  1. Select a tool – pick a color, decode a code or create a palette.
  2. Type in your color, or choose it from the color picker (either HEX or RGB).
  3. Copy your result — exact code/palette desired — ready to use!

Who these tools are for

  • Web designers who carefully choose colors and confirm the color codes before passing over a design.
  • When developers need to translate or convert between HEX and RGB, but the design spec and codebase are not the same format.
  • Brand & marketing teams developing a unified color palette for a new project.
  • Pupils and enthusiasts discovering the theory and practice of color harmony, such as complementary and analogous colors.
  • For anyone who requires a rapid and accurate colour code without using a full design application.

Frequently Asked Questions

Are these colour tools cost free?

Yes. These are all 100% free to use and don't require any sign-up.

What is the difference between HEX and RGB colour codes?

HEX is a code with 6 characters; similar to: The color #3366FF is commonly used in web design and in CSS, and RGB is the same color, but it is represented by three numbers representing red, green and blue. They both share the same colors, but they are just different file formats, which is why sometimes it is necessary to convert from one format to the other.

Which color schemes are available in Palette Generator?

Complementary, analogous, triadic, and monochromatic schemes, which are all based upon actual color theory and not random colors.

May I use the color codes as is?

Yes — HEX and RGB values can be copied with a single click – is immediately available after picking a color or creating a palette.

Is there design experience required to use Palette Generator?

No, just select a starting color and select a scheme, and The Tool creates a matching palette for you without needing any color theory.

Are these tools available on mobile?

Yes, all four tools are cross browser compatible and work in any modern mobile or desktop browser.

Will the colour I choose appear the same on all screens?

The HEX/RGB values themselves are accurate and will display the same color everywhere where they are called, although the color may be slightly different depending on the color calibration of each screen.
