How to Transform RGB Colors into Hex Quickly

Let's start in that wonderful, magical moment of pure, creative flow. You're a designer. You're working in a program like Photoshop, Illustrator, or Canva. You're playing with the visual color picker, you're sliding the different toggles around, you're exploring the different shades, and then, you find it. The absolute, perfect, most beautiful shade of blue that you have ever seen. It’s the perfect color for your new logo, for your website's background, or for your latest digital illustration. The program tells you what its value is: it’s R: 36, G: 113, B: 163.

You are thrilled. But now comes the next step. You have to hand this perfect color over to the web developer who is going to be building the website for you. But the developer comes back and tells you that they need the color in a completely different format. They don't need those three, separate numbers. They need that strange, single, six-digit "hex code."

You have the perfect color, but it feels like you are speaking a completely different language than your developer. So how do you accurately and perfectly translate your beautiful, intuitive RGB color into the technical language of the web? Well, you could try to do some complex and confusing math. But who has the time for that? The instant, the simple, and the completely foolproof solution is an online converter, a tool that acts as the perfect translator between the world of visual design and the world of code.

The Designer's Language: A Quick Refresher on RGB

Before we get into the translation process, let's just quickly remind ourselves why RGB is such an intuitive and human-friendly way to think about color. RGB stands for Red, Green, and Blue, and it is what is known as an "additive" color model.

The best and the simplest way to think about it is to imagine that you are a lighting designer for a completely dark stage. You have three, very powerful spotlights at your disposal: one is a pure, vibrant red, one is a pure, bright green, and one is a pure, deep blue. By changing the intensity or the brightness of each of these three different lights, you can mix them together to create any color that you can possibly imagine. In the digital world, that intensity is measured on a simple scale that goes from 0, which is completely off, all the way up to 255, which is full, maximum brightness. This is the native language of almost all design software, and it is the language that our screens themselves use to produce color.

The Developer's Shorthand: Why the Web Loves Hex

So, if RGB is so simple and so intuitive for us humans to understand, why do web developers almost always prefer to use that strange, hexadecimal code in all of their CSS and their HTML?

The main reason comes down to conciseness. A single, six-character hex code, like #2471A3, is much shorter, it is cleaner, and it is so much easier to quickly copy, to paste, and to read in a long line of computer code than its RGB equivalent, which is rgb(36, 113, 163). It is, at its heart, a very efficient form of shorthand that helps to keep the code clean and easy to manage.

It has also been the accepted web standard for decades. It is a completely universal and instantly understood format for defining color in the world of web design. And finally, because it is a single, unbroken string of text, it can actually reduce the chance of making a simple typo when you are compared to trying to correctly type out three, separate, and often very similar, numbers.

The Manual Conversion: From Decimal to Base-16 (A Quick Warning)

Now, you might be a curious person, and you might be thinking, "Okay, so how would I actually convert my RGB numbers into a hex code by hand?" Well, I am happy to explain it to you, but I can also tell you right now that you will probably never, ever want to do it yourself.

To go from an RGB value, which is a regular, base-10 decimal number, to its hex equivalent, you have to convert it into a base-16 number. The way you do this is by dividing your number by 16. The whole number that you get is your first digit, and the remainder is your second digit. And you have to remember that in the world of hex, the number 10 is an A, the number 11 is a B, and so on.

Let’s try it with the number 163. If you divide 163 by 16, you get 10, with a remainder of 3. So, the first digit is 10, which is an A, and the second digit is 3. So, the decimal number 163 is A3 in hexadecimal. As you can see, it is a confusing, multi-step, and highly error-prone mathematical process that no busy, creative professional should ever have to waste their precious time on.

A World of Scenarios: The Constant Need for Translation

This process of converting from the designer's language of RGB to the developer's language of Hex is not some obscure, rare task. It is a constant and an everyday necessity in almost any digital, creative workflow.

Imagine you are a graphic designer, and you have just finished creating a beautiful and comprehensive brand guide for a new company. You have used your design software to pick out the perfect primary and secondary colors for the brand, and your software is telling you what those colors are in their RGB values. Before you can hand that guide over to the company's web development team, you will need to provide them with the corresponding hex codes for every single one of those colors.

Or, imagine you are a digital artist, creating a beautiful illustration in a program like Procreate on your iPad. You mix and you blend until you find the absolute perfect color for the sky in your painting. You now want to use that exact same, perfect color for the background of your online portfolio website. You will need to take the RGB value from Procreate and convert it into a hex code for your website's CSS. This constant need for translation is an unavoidable part of our modern, creative lives.

It ensures perfect, technical precision.

But there is one, very important thing that the tool cannot do. It cannot tell you if that is the right shade of blue for your company's new logo. It cannot tell you if that particular shade of blue is going to clash horribly with the bright orange color that you have chosen for your call-to-action button. Your incredible skill as a designer, your deep and hard-won understanding of color theory, and your knowledge of your brand's unique identity that is what makes your design good.
