RGB to HEX Converter

Q: How do I convert RGB to HEX color?

You can convert RGB to HEX code as follows: Write down the RGB values : three integers between 0 and 255, representing red, green, and blue, respectively. Convert each of them into a hexadecimal number . We need two-digit hexadecimal numbers. If need be, add a leading zero : 04 for 4 , or 0A for A . Combine the three hex digits into one string and adorn it with the hash # prefix . RGB to HEX color conversion is ready!

Q: What is RGB (0, 128, 0) color?

RGB code (0, 128, 0) means that only green light is present and at half intensity . This means that RGB (0, 128, 0) corresponds to dark green. Converting this RGB to HEX color gives #008000 .

Q: How do I encode gray as RGB?

In RGB, we produce gray by requiring equal intensity of all ingredients , hence gray corresponds to RGB codes (N, N, N) where N is any integer between 1 and 254. Note that N = 0 gives black (no light) and N = 255 gives white (full intensity). We can see that gray interpolates between black and white.

Our RGB to HEX converter is here to assist with all tasks that involve converting RGB to HEX codes. Have you just found the perfect color for your project, and the last thing missing is to convert its value in RGB to HEX code? Or do you need to learn how the RGB to HEX conversion works mathematically for the sake of your web design class? Let us dive into it together!

What is the RGB color system?

The RGB color model is what makes your smartphone's screen appear so vibrant and colorful. It relies on three basic ingredients — Red, Green, and Blue — and mixes them in appropriate proportion to generate a vast spectrum of colors.

The idea behind RGB is to express each color as three numbers, each representing the intensity of red, green, and blue, respectively. The intensities can range from 0 to 255. For instance:

(255, 0, 0) represents pure red;
(0, 0, 128) corresponds to a dark (navy) blue;
Equal mixture of intense red and green (255, 255, 0) produces yellow;
A total absence of light (0, 0, 0) means black; and
Full intensity of all three ingredients, (255, 255, 255), produces white.

Before we explain how to convert RGB to HEX code, we need to understand the principle behind the HEX system. Spoiler: HEX is not a different color system, just a different way of encoding RGB colors. If you want to discover other color systems, check out Omni's color converter.

What is the HEX color system?

HEX is not a replacement for RGB. It is simply a different way of writing RGB colors, which is more useful from the point of view of programming languages. Rather than listing three comma-separated decimal numbers, HEX converts each of them from a decimal to a hexadecimal number and then concatenates them into a single string, adding also the prefix #.

For instance:

RGB (0, 0, 255) becomes #0000FF;
RGB (128, 128, 0) becomes #808000; and
RGB color (255, 255, 255) becomes #FFFFFF

FAQs

What is RGB (0, 128, 0) color?

RGB code (0, 128, 0) means that only green light is present and at half intensity. This means that RGB (0, 128, 0) corresponds to dark green. Converting this RGB to HEX color gives #008000.
