How to Change Color of Selected Cells in Excel 2007

Manual Color Change
1. Highlight the selected cells you wish to change color. Hold the left mouse button down while running your mouse pointer over the selected cells, provided the cells are continuous. If the cells do not touch each other and are more selective, you can hold the Ctrl (Control) button as you click each cell you wish to highlight.
2. Select the 'Home' tab on the top tool bar. Underneath 'Home' should be seven sections, with labels on the bottom of each section. The section names should be: 'Clipboard,' 'Font,' 'Alignment,' 'Number,' 'Styles,' 'Cells' and 'Editing.'
3. Click the down arrow next to the icon that looks like a paint can, located in the 'Font' section. Select one of the 'Theme Colors' or 'Standard Colors' by clicking on the colored box representing the color you want. If you don't see the desired color, click 'More Colors...' for more standard and custom color options. Once you have clicked on the desired color, the cells you highlighted will change to the color you selected.
Automatic Color Change
4. Highlight the selected cells you wish to change color. Excel 2007 offers conditional formatting enabling you to set the cells to automatically change color based on the rules you set.
5. Select the 'Home' tab on the top toolbar. Click on 'Conditional Formatting' in the 'Styles' section. A drop-down box will appear with options.
6. Move your mouse over 'Highlight Cells Rules' at the top of the drop-down box. Another box will appear to the side listing the most common rules used, plus an option to select 'More Rules...' should you not immediately find what you need.
7. Select 'Greater Than...' or the rule most appropriate for your formatting. If you use 'Greater Than...,' a small box will pop up with the cursor automatically in a blank box on the left and color descriptions in a box on the right of the little screen. The same box will appear for all represented rules, but with different titles for the purpose of the rule's function.
8. Enter the value that highlighted cells should be greater than in order to change color. Click the drop-down arrow next to the color description box on the right, and select one of the predetermined cell formats, or select 'Custom Format...' to create your own rules on how the cells should look. Click OK when you are done. Your cells will now change color depending upon the number entered.
