The Web-safe palette, also known as a 216-color palette, was chosen by Netscape in the early years of the Web to ensure colors appeared the same across all hardware, as many computers were unable to display more than 256 colors. This palette is still frequently used today for complete compatibility, even though most computers now offer 16.8 million colors. The 216 colors come from dividing the 256 colors by 6, resulting in hexadecimal values of 00, 33, 66, 99, CC, and FF, which, when combined, create web-safe colors for use on the Internet.
FAQ About the 216-Color Palette
The 216-color palette or Web-safe palette is a widely used term in web design. It has been a topic of interest for many people who work with colors, especially in the digital world. Here are some frequently asked questions about the 216-color palette:
What is the 216-color palette?
The 216-color palette, also known as the Web-safe palette, is a set of 216 colors that are guaranteed to look the same across all computer hardware. It was selected by Netscape in the early days of the web when many computers could only display 256 colors. Although most computers now offer millions of colors, the 216-color palette is still used to ensure full compatibility.
Where does the number 216 come from?
The number 216 is the result of the cube root of 256. When red, green, and blue (RGB) are given equal weight, the 216 originates from 6x6x6, which is the largest cube that fits inside of 256 but does not go beyond it. The result of dividing the 256 colors by 6 is the hexadecimal values 00, 33, 66, 99, CC, and FF. Any combination of R, G, and B with these values creates a web-safe color.
Why is the 216-color palette still used?
Although most computers today offer 16.8 million colors, the 216-color palette is still used to ensure full compatibility across different browsers and platforms. Some legacy systems and devices may still have limited color options, and using the 216-color palette guarantees that the colors will appear correctly regardless of the platform.
Can I use other colors besides the 216 on my website?
Yes, you can use any color you want on your website. However, using colors outside of the 216-color palette may result in inconsistency across different devices and platforms. Colors that are not web-safe may display differently on different monitors, which can affect the design and user experience of your website. As such, it’s best to stick with web-safe colors as much as possible.
