1 HTML Basics - HEX and RGB colors on Tue Nov 15, 2011 7:18 am

Below are a table with basically 9, the most important colors. You must learn these codes, and all description which are here:

HEX Color
RGB Color
Background color (Preview)
Color name

- The definiton of RGB is simple => RedGreenBlue;

- Also, HEX is named hexadecimal;

- Note, that HEX color is similar to RGB in the point of view that RGB are the same as HEX, but only the structure is not that; tongue

- (255,0,255) => #FF00FF, so... 255(red) have a maximum value, 0(green) don't have a value, or the value is minimal, and the third 255(blue) value is maximum too. Please note, that 255=FF / 0=00 / 255=FF.

More colored examples to be more easy to learn:
rgb(255,0,192) = #FF00C0;
rgb(55,192,255) = #37C0FF;
rgb(100,150,200) = #6496C8;
rgb(192,255,192) = #C0FFC0;
rgb(192,0,50) = #C00032.

- The biggest value is rgb (255) or HEX #FF / #F, and the smallest rgb (0) or HEX #00 / #0;

- The HEX's value can be abbreviated. So, you can change #0088FF into #08F. How this works? Very simple: 0, 8 and F doubles. Attention: the result is the same;

- So RGB, as HEX colors, have more than 16 million different colors according the W3Schools. A simple calculation: (256x256x256), why 256 and not 255? Logical, 0 is the first value, and 255 the last.
0 = 1;
1 = 2;
2 = 3;
3 = 4;
254 = 255;
255 = 256;

HTML Code example & description:
Here are a little example:<br/ >
<font color="#FF0000">Hello {USERNAME}</font>
The same color, but simply another text:

<font color="#F00">How are you {USERNAME}</font>
As you can see, the color is the same (#FF0000 / #F00);
The font tag is used to grant ter the color attribute+value: color="#F00";
Also, you can use in CSS Stylesheet these codes to providing a color:
color: #0088FF;
and the HTML code:
<span class="class1">Hello {USERNAME} at Gassy</span>
I don't want to complicate you, for CSS lessons after some time... Wink
