    Hex2RGB | An Animated Guide to Hex Codes

This is a animated guide to what hex codes are, and how to convert them to RGB.  Knowing this can make it easier to adjust, or understand your colors when all you have is the hex code. There a some interactivity and animations that make this guide semi-engaging.

				Hex codes are away to communicate a color value, to our browsers and eventually the computer. These are very similar to hsl and rgb values. Hsl and rgb have a clear and easy to read syntax. Hex codes unfortunately have a much more confusing syntax.

			Hex codes are comprised of 6 values. There are 3 pairs of values in a hex code. The first two numbers show how much <span class="red">red</span> should be added. The next tell how much <span class="green">green</span>, and the next tells how much <span class="blue">blue</span> to add. This kind of sounds a lot like RGB.

		<h2>Under the hood</h2>
		<p>
			So we now know that hex codes are just pairs of values that represent <span class="red">red</span>, <span class="green">green</span>, and <span class="blue">blue</span> amounts. Which is kind of like rgb. Its actually even closer to rgb than just that. The values in hex code start at 0 and go to 255, just like in rgb.

			Obviously RGB and HSL values are much easier to write and more human friendly than hex codes are. However, now you know that hex codes are not just some globity-gook mess only computers can read, and are really closley related to rgb. Now that you know the basics you can kind of guess that
			#ff 00 00 is going to look red since is pair are the only ones that have a value, or #05ff22 is going to look greenish due how much green it has.

	Hex codes are away to communicate a color value, to our browsers and eventually the computer. These are very similar to hsl and rgb values. Hsl and rgb have a clear and easy to read syntax. Hex codes unfortunately have a much more confusing syntax.

	Hex codes are comprised of 6 values. There are 3 pairs of values in a hex code. The first two numbers show how much <span class="red">red</span> should be added. The next tell how much <span class="green">green</span>, and the next tells how much <span class="blue">blue</span> to add. This kind of sounds a lot like RGB.
	</p>
	</section>
	<section class="hex-converts-to">
	<h2>Under the hood</h2>
	<p>
	So we now know that hex codes are just pairs of values that represent <span class="red">red</span>, <span class="green">green</span>, and <span class="blue">blue</span> amounts. Which is kind of like rgb. Its actually even closer to rgb than just that. The values in hex code start at 0 and go to 255, just like in rgb.

	Obviously RGB and HSL values are much easier to write and more human friendly than hex codes are. However, now you know that hex codes are not just some globity-gook mess only computers can read, and are really closley related to rgb. Now that you know the basics you can kind of guess that
	#ff 00 00 is going to look red since is pair are the only ones that have a value, or #05ff22 is going to look greenish due how much green it has.
