Subject: [PATCH] Added example, explanation and solution to "Use RGB to Mix
 Colors" (#34613)

* Added example, explanation and solution to "Use RGB to Mix Colors"

* Keyword backtick changes

-As suggested earlier, I changed the triple backticks of the keywords into single backticks

* Consistent style and format changes

-Changed the spacing of the '<style>' elements , in order to create consistent spacing, and removed extra words to fit the quotes

* fix: removed older examples

 title: Use RGB to Mix Colors

 ## Use RGB to Mix Colors
-<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds  -->
-An RGB value is a combination of values for red, green, and blue (RGB).  Each perameter defines the intensity of the color as an integer between 0 (no color; black) and 255 (highest intensity) or a percentage from 0% to 100%. For example: 
-```css
-rgb(255, 0, 0)
-```
-This is rendered as red, because the red parameter is set to its highest value (255) and the others are set to 0. With RGB, you can mix colors by using combinations of different values.
 
-### Examples:
-```css
+## Problem
+```html
 <style>
-h2 {
-  color: rgb(0, 0, 255);
+  .red-text {
+    color: #000000;
+  }
+  .orchid-text {
+    color: #000000;
+  }
+  .sienna-text {
+    color: #000000;
+  }
+  .blue-text {
+    color: #000000;
+  }
+</style>
+```
+
+## Objective
+Within the `<style>` element, we need to change the hexcode colour  `#000000` within the `color` element in these classes:
+* `.red-text`
+* `.orchid-text`
+* `.sienna-text`
+* `.blue-text`
+
+We are provided a table where the table shows the RBG values of the colours for these required classes shown here:
+
+| Colour | RGB |
+|:--------:|:-----:|
+|Blue|rgb(0, 0, 255)
+|Red|rgb(255, 0, 0)
+|Orchid|rgb(218, 112, 214)
+|Sienna|rgb(160, 82, 45)
+
+## Example
+In order to change the hexcode colour of a class within the style element, we simply replace the hexcode itself with the RGB value shown below.  
+
+### Before
+```html
+<style>
+  .ClassName {
+    color: #000000;
 }
 </style>
 ```
-Above is RGB is used to turn an h2 element blue.
-```css
+
+### After
+
+```html
 <style>
-h2 {
-    color: rgb(64, 224, 208);
+.ClassName {
+  color: rgb(255, 255, 255); /*this represents the rgb value of the colour, white*/
 }
 </style>
 ```
-In this example above, different values of RGB are combined, and 'color: rgb(64, 224, 208)' turns the h2 elements turquoise.
 
+**Note:** In the class,`.ClassName`, within the `<style>` element, the color has changed from a hexcode of `#000000` into the rgb value, `rgb(255, 255, 255)`, which shows that the color of the class `.ClassName` has changed from black to white in the `<style>` element.
+
+## Solution
+From the Problem above, we need to change `#000000` from the `color` element in the `<style>` element, into the given RGB values from the table based on the colour that the class needs. For example, the class `.red-text` clearly needs their `color` element to be changed from `#000000` into a red colour, where the table gives us the rgb value of rgb(255, 0, 0) for the colour red, which is shown below:
+
+### Before changing `color` of class `.red-text`
+```html
+<style>
+  .red-text {
+    color: #000000;
+}
+</style>
+```
+
+### After changing `color` of class `.red-text`
+```html
+<style>
+.red-text {
+  color: rgb(255, 0, 0); /* Color has changed into red when we used this rgb value from the table*/
+}
+</style>
+```
+
+We will follow the same steps for the rest of the classes shown here:
+
+### Before changing `color` of other classes
+```html
+<style>
+  .orchid-text {
+    color: #000000; 
+}
+  .sienna-text {
+    color: #000000; 
+} 
+  .blue-text {
+    color: #000000; 
+}  
+</style>
+```
+
+### After changing `color` of other classes
+```html
+<style>
+  .orchid-text {
+    color: rgb(218, 112, 214); /*Color has changed into orchid when we used this rgb value from the table*/
+}
+  .sienna-text {
+    color: rgb(160, 82, 45); /* Color has changed into sienna when we used this rgb value from the table*/
+}
+  .blue-text {
+    color: rgb(0, 0, 255); /* Color has changed into blue when we used this rgb value from the table*/
+}
+</style>
+```
+
+## Final Solution
+Hence, the final solution reveals that we have changed the `color` element of these text classes with rgb values shown below:
+```html
+<style>
+  .red-text {
+    color: rgb(255, 0, 0);
+  }
+  .orchid-text {
+    color: rgb(218, 112, 214);
+  }
+  .sienna-text {
+    color: rgb(160, 82, 45);
+  }
+  .blue-text {
+    color: rgb(0, 0, 255);
+  }
+</style>
+
+<h1 class="red-text">I am red!</h1>
+
+<h1 class="orchid-text">I am orchid!</h1>
+
+<h1 class="sienna-text">I am sienna!</h1>
+
+<h1 class="blue-text">I am blue!</h1>
+```
