How to add color in my matrix?

[saranp780]

Now I have a matrix that contains the valuable information. I want to add color to the value for making it easy to present. 

If the value is greater than 15, I want to show that critical as a red color.

If the value is between 7-14, I want to show that medium as a yellow color.

If the value is less than 6, I want to show that low as a green color.

Now I use the matrix visualization in which in the yellow box.  

So, I would like to ask somebody that can help me solve the problem.

Best regard.

This is how you do that (see picture attached):

1. Select Format pane

2. Select Conditional Formatting and choose column for which you would like to apply conditional formatting

3. Select Font Color scales and press Advanced Control

4. Select Color by rules

5. Define your conditional formatting logic
