COLORCALC™

Sorry, your browser is unable to run Java applets!

Use the WWWeb Color Calculator™ to select background and foreground colors that are easy to read and go well together. Click the radio buttons to switch between background and foreground (letter) colors. Adjust the colors using the sliders. Clicking on the left or right triangles subtracts or adds one. Clicking in the area to the right or left of the thumb slide subtracts or adds ten. You can also change the color by dragging the slide to a new position.

New in Version 1.1

Now you can enter a hex triplet directly into ColorCalc. When you click the Set button the new color is applied to either the background or foreground depending on which you have selected.
Click the Swap button to swap the background and foreground colors.

Use the six-digit hex numbers from the bottom of the calculator or the three decimal numbers adjacent to the sliders in your HTML, Java or JavaScript files to specify colors. Bear in mind that which ever colors you pick, the colors seen by your readers are limited by their hardware and/or settings. See Using Color in Web Pages for more information.
