Ultimate RGB to HEX Converter for easily converting an RGB value to HEX on value any devices. Use our superfast RGB to HEX Converter just like this: type the RGB values or use the RGB sliders and the HEX value is displayed immediately.

**How does this RGB to HEX converter work?**

Converting an RGB color code to HEX format online is now super-easy. **Our RGB to HEX converter takes input in the form of RGB values and then converts the RGB codes to a hexadecimal code that can be used in web design and web development** (for example HTML & CSS coding). As you enter any RGB colour value, the HEX value is displayed immediately, sol you don’t even need to hit the Convert button. You can also use the RGB sliders to set the initial R, G, and B values.

**What is RGB color code?**

RGB code based on the addictive RGB color model in which Red, Green and Blue light are added together to reproduce almost any color. **RGB color code consists of three decimal numbers ranging from 0 to 255.** A typical RGB color code looks like this: (123, 45, 0)

**What is HEX color code?**

**HEX color code or hexadecimal color code a set of letters and numbers that correspond to red, green, and blue values**. Combining these numbers and letters produces the same broad range of colors as RGB code. A typical HEX color code looks like this #7b2d00 (which is the equivalent of the RGB color code mentioned in the example above).

**How to convert a color value from RGB to HEX?**

**RGB values are in decimal number system format and HEX color values are in hexadecimal number system format** so if you want to convert an RGB color code to HEX color code, you should be familiar with the decimal to hexadecimal conversion.

The hexadecimal digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e and f, so ‘a’ is equal to 10 in decimal, ‘b’ is equal to 11 in decimal and so on. Back to the RGB to HEX conversion, in order to convert an RGB color code to a hex color code, you will need to convert each of the values (r, g, and b) individually. **Decimal to hexadecimal conversion** can be achieved by applying the repeated division and remainder algorithm. The essence of the algorithm is that the decimal number is repeatedly divided by the radix 16. In between these divisions, the remainders give the hex equivalent in reverse order. So for example, if the R value is 123, then you can get its hexadecimal equivalent like this:

- Take the number
**123**, and divide by 16. 123 / 16 = 7.6875, which means that the first digit of hex color code is**7**. - Take the remainder of the first digit,
**0.**6875, and multiply by 16. 0.6875 (16) = 12, which means that the second digit of the hex color code is 11, or B. - So the R value in HEX is 7b.

**To get the HEX value of the RGB code you have to repeat this algorithm on each of the RGB numbers**, but of course, if you don’t want to waste your time,** you can also use our superb RGB-to-HEX Converter**.
