Change the border color of multiple cells of any selection

Sometimes you may want to change the cell border color for specific selections for some reasons. And you can do it with the following steps:

Step 1: Click the arrow beside the Border button in the Font group under the Home tab.

Step 2: In the drop-down list, move the mouse over the Line color item, and select fit color. See the following screenshot:

Step 3: Then the cursor becomes a pencil. Please hold down the Ctrl key, and drag the pencil through the selection that you want to change its cell border color.

Then the border color of all cells in the dragging through ranges is changed to the color that you set in Step 2.

Change the border color of all cells in the whole worksheet (gridline color)

Sometimes you may want to change the gridline color or the border color of all cells in the wholes worksheets. You can do it with the following steps:

Step 1: In Excel 2010, Click the File >> Option to get into the Excel Options dialog box; in Excel 2007, click the Office button >> Excel Option.

Step 2: In the Excel Options dialog box, click the Advanced button at the left bar.

Step 3: Scroll to the Display options for this worksheet section, and select the current working worksheet.

Step 3: Find out the Gridline Color item, and click the  Fill color button to change the gridline color.

Step 4: Click the OK button.

Then you will see the gridline color is changed to the new set color, which means the border color of all cells in the current worksheet is changed to the new set color.
