How do I make certain cells different colors in excel?

Excel allows users to customize the appearance of cells in a spreadsheet. One common customization is to change the fill color of cells to make certain data stand out or to color code information. There are several ways to change the cell color in Excel depending on your needs.

Using Automatic Cell Color Formatting

The easiest way to color cells in Excel is to take advantage of the automatic formatting options. These allow you to quickly color cells based on the value or data contained within them. Some common automatic options include:

  • Data bars – Color cells with gradient fills based on the numeric value. Higher values have darker gradient fills.
  • Color scales – Color cells with gradient fills based on relative values. Lower values are one color, mid values are white, and higher values are a different color.
  • Icon sets – Display icons in cells based on value thresholds. Common icon sets include traffic light indicators (red, yellow, green).
  • Rules – Color cells that meet custom criteria you define. For example, color all cells greater than a value.

To use automatic cell coloring:

  1. Select the cells you want to color format.
  2. On the Home tab, click the Conditional Formatting dropdown and select your desired formatting option.
  3. In the dialog box, customize the formatting settings as needed.
  4. Click OK to apply the cell fill colors.

The advantage of automatic formatting is that it’s very quick and the coloring will update dynamically when cell values change. The downside is you have limited control compared to manually setting colors.

Manually Filling Cells

For full control over cell fill colors, you can manually set the color of cells:

  1. Select the cells to color.
  2. On the Home tab, click the Fill Color dropdown and select the desired color.

This will immediately fill the selected cells with that color. You can choose from standard theme colors, custom colors, or gradient fills here.

Some tips for manually filling cells:

  • To color code data, select a range then use Ctrl + Click to select and color additional cells.
  • You can fill cells with patterns or even images via the Fill menu.
  • Use the Eyedropper to pick up a color from other colored cells.

The advantage here is you have full control. The downside is having to manually reapply if data changes.

Using Cell Styles

Cell styles allow you to define a custom cell formatting and then apply it with one click. This can include a cell fill color. To use styles for coloring cells:

  1. Select the cells to color.
  2. On the Home tab, open the Cell Styles gallery.
  3. Hover over various styles to preview colors, then select your desired style.

This will color the cells along with applying any other formatting defined in that style.

You can also create custom styles with your preferred colors:

  1. Select a cell and manually format it (fill color, font, borders, etc).
  2. On the Home tab, click the Cell Styles dropdown and select New Cell Style.
  3. Name your custom style.
  4. Click OK to save.

Cell styles help streamline applying colors, especially if reusing the same colors in many places. Just remember to update the style itself if you need to change the colors.

Using Themes

Themes are another way to quickly color cells in Excel. A theme applies predefined colors to various elements of your spreadsheet:

  • Column/row headers
  • Data cells
  • Accent colors for graphical elements
  • Font colors

To use a theme for coloring cells:

  1. On the Page Layout tab, click Themes to view the theme gallery.
  2. Hover over a few themes to see the colors change on your spreadsheet.
  3. Click the theme you want to apply.

This will change the color scheme of your spreadsheet, including cell fill colors. You can customize the colors for a theme via the Theme Colors menu. The advantage is quickly changing the overall look. The downside is lack of control over individual cells.

Coloring Rows or Columns

You can also quickly color entire rows or columns in Excel, as opposed to individual cells:

  • Rows – Select the row number(s) on the left, then choose a fill color.
  • Columns – Select the column letter(s) at the top, then choose a fill color.

This is a good way to make alternating rows or columns different colors for readability. However, it colors all cells so there is no flexibility. You can combine this with other coloring methods described above.

Using VBA Macros to Color Cells

For advanced cell coloring needs, you can use VBA macros to color cells. Some examples where macros are helpful:

  • Color all cells with a dynamic value (formula result, Now() date, etc).
  • Color cells matching a complex criteria not supported by default rules.
  • Loop through and color a large number of cells programmatically.

Here is an example VBA macro to color cells based on value:

Sub ColorCells()
  Dim cell As Range
  For Each cell In Range("A1:D10") 
    If cell.Value > 5000 Then
      cell.Interior.ColorIndex = 3 'red
    ElseIf cell.Value > 1000 Then  
      cell.Interior.ColorIndex = 6 'yellow
      cell.Interior.ColorIndex = 5 'green
    End If
  Next cell
End Sub

This loops through the range A1:D10 and colors each cell red, yellow, or green based on the value. The full color index codes are:

Index Color
1 Black
2 White
3 Red
4 Green
5 Blue
6 Yellow

VBA gives you the most flexibility, but requires more coding knowledge. Start slow and simple until you build skill.


Coloring cells in Excel provides visual cues about your data. The key options include:

  • Automatic formatting with data bars, color scales, etc
  • Manually filling cell colors
  • Using cell styles for reusable colors
  • Applying color themes
  • Coloring full rows/columns
  • VBA macros for advanced cell coloring

Think about your specific needs and data. Use automatic options for quick convenience, but manually fill or use styles for more control. VBA provides the most flexibility when needed. Proper use of color can make your spreadsheets easier to understand and analyze.
