Use ToolQuick start
The color picker at the top of this page covers most everyday tasks. Follow these steps, then open a dedicated tool when you need something more specific.
Click the color wheel or press Random Palette. Use the color format menu to view the selected color as HEX, RGB, HSL, HSV or OKLCH.
Select complementary, split complementary, analogous, triadic, tetradic, square or monochromatic. The matching colors appear in the palette panel next to the wheel.
Copy any swatch with its copy button, or open Export Color Codes to get Tailwind v4, Tailwind v3, Figma, CSS or plain color codes.
Switch between shades, tints and tones to build a full scale from one color. The simulator shows how your palette may appear with protanopia, deuteranopia or tritanopia.
Convert values with HEX to RGB or RGB to HEX, test readability with the Color Contrast checker, or sample a photo with the Image Color Picker.

About Tool Web
Free online color tools - It allows you to select, modify, blend, compare, and test colors directly within your browser—no software installation required. 'Tool Web' brings together a color picker, HEX-to-RGB and RGB-to-HEX converters, a color wheel, a color mixer, a contrast checker, and an image color picker, all in one place.
A color might look perfect on a screen, yet prove difficult to reuse; this is because design files, CSS, and brand guidelines often define it in different ways. For instance, the same shade of blue could be represented as #3B82F6 in HEX, rgb(59, 130, 246) in RGB, or as an oklch() value in modern CSS. 'Tool Web' provides you with the exact value you need, ensuring color consistency from the design file all the way to the production code.

Most color tasks are small, but they happen constantly. Tool Web is built to make each one quick and easy to repeat.
A picker, converters, mixers, a color wheel, a contrast checker, an image color picker, color names, charts, and a library—all of these are available on a single website, so you don’t need a separate website for each task.
Work in HEX, RGB, HSL and HSV, and in OKLCH, a modern CSS color format based on perceived lightness, chroma and hue.
Instead of retyping color values by hand, export the palette for Tailwind v4, Tailwind v3, Figma, or CSS.
Test text and background combinations against WCAG standards, and preview the colors using a color-blindness simulator before they reach production.
The color tools are free to use and open in your web browser, so there is nothing to install.
Learn the ideas behind the tools, from color contrast ratio and WCAG levels to tints, shades and tones and color psychology in branding.
Find answers to common questions about our services
Free online color tools are web-based utilities that assist you in selecting, converting, mixing, comparing, and verifying colors. Instead of opening design software, you can use these tools directly in your browser to find color codes, convert them between formats like HEX and RGB, create palettes, or test for readability.
The tool offers a web color picker, color wheel, color mixer, HEX-to-RGB and RGB-to-HEX converters, a color contrast checker, an image color picker, a color chart, a reference for color names, and a color library. The picker located at the top of the page also includes features for color harmonies, export options, and a color blindness simulator.
Select a color using the 'picker' or 'Color Picker' tool on this page; doing so will display its HEX code along with a preview. If the desired color is found within an image, screenshot, or logo, upload it to the 'Image Color Picker' and select the specific pixel you prefer.
Divide the six-digit HEX code into three pairs and convert each pair from base 16 into a number between 0 and 255. For example, #3B82F6 converts to rgb(59, 130, 246). A HEX-to-RGB converter tool performs this task instantly, while also displaying HSL, HSV, and CMYK values.
The color picker displays HEX, RGB, HSL, HSV, and OKLCH. OKLCH is a modern CSS color format based on perceived lightness, chroma, and hue. The HEX-to-RGB converter also includes CMYK, while the RGB-to-HEX converter provides a HEX code.
Under WCAG Level AA, a minimum contrast ratio of 4.5:1 is required for normal text, and 3:1 for large text. For Level AAA, these ratios are 7:1 and 4.5:1, respectively. Check your colors using a 'Color Contrast Checker'.
Yes. By using the 'Export Color Codes' feature on this page, you can copy your palette for Tailwind v4, Tailwind v3, Figma, or CSS in HEX, RGB, HSL, or OKLCH formats. You can also choose to copy just the plain color codes.
Yes, the simulator on this page provides a preview of your palette as it would appear to individuals with protanopia, deuteranopia, or tritanopia. This serves as a quick design check—not a substitute for accessibility testing with actual users—so be sure to combine it with a contrast check.
Yes. The color-related tools on 'Tool Web' are free to use and open directly in your web browser, so there is no need to install anything. Simply select a tool from the list above and get started.
