RGB Values for Automatic Colors

Paul generates a lot of XY plots in Excel. Sometimes he wants to change the colors of the markers and lines of one series to match those of another series. He would like to match the "automatic" colors that Excel applies, but Paul hasn't found a way to get a list of the RGB values for the "automatic" colors. When he manually selects colors for a series a dialog box opens showing theme colors, standard colors, and recent colors. Oddly, none of these are the same as the automatic colors. Paul wonders if anyone knows how to identify the RGB values of Excel's automatic colors.

To discover a chart line's RGB value, as assigned by Excel, follow these steps if you are using Excel 2013 or a later version:

  1. Right-click on the data series (the line) in the chart. Excel displays a Context menu.
  2. Choose Format Data Series. Excel displays the Format Data Series task pane at the right of the screen.
  3. In the task pane click the Fill & Line option. (This option looks like a spilling paint bucket.)
  4. Expand the Line options, if necessary.
  5. Click the Color tool. Excel displays a palette of colors you can use.
  6. Choose More Colors. Excel displays the Colors dialog box. The Custom tab should be displayed, by default, in the dialog box. (See Figure 1.)
  7. Figure 1. The Custom tab of the Colors dialog box.

The RGB values shown in the dialog box are the values for the currently selected data series. Jot them down and then you can close all the dialog boxes and the task pane.

The above steps (or their equivalent, adjusted for interface differences) won't work in Excel 2007 or Excel 2010. The reason is because Excel doesn't make the Color tool available in the Format Data Series dialog box as it does in Excel 2013 and later versions. (The tool is hidden if the line type is set to Automatic.) So, you must resort to a different technique.

Perhaps the quickest way to find out the RGB values of a color is to use a specialized tool outside of Excel. A class of tool known as a "color picker" can be used to show the color of any pixel on the screen—including those used in a chart line. The following are a few different color pickers you can check out:

https://www.picpick.org

This list of suggestions isn't exhaustive, by any means. You should be able to do a web search for "color picker" (with the quotes) and find literally scores of such utilities.

When working with automatic colors in charts, remember that Excel can and often does change them whenever a chart is regenerated. (They are automatic, after all.) This is particularly true if you change a single data series so it is no longer automatic of if you add to or remove from the chart's underlying data.

Hi Kia

Try the Colours button, near the left-hand end of the Page Layout tab in Excel.

This gives a menu of different colour combinations for the default colours used by Excel throughout the workbook (so not just the currently selected chart/cell etc)

Use the Customise Colours option at the bottom of the menu to create your own colour set. By default, charts use the colours accent 1 to accent 6. Give your colour set a name using the box at the bottom of the dialog box and click Save to save and apply the colours.

This changes the colours which appear in the colour pickers for font, border and fill, and the default colours used in charts and SmartArt diagrams. Once you have saved a colour set in one workbook, it will be available on the colours button in other workbooks, and also available in Word and PowerPoint (look on the Design tab).

regards

Paul

Hi there,
Is there anyway of changing the colours that excel automatically chooses for its charts and line graphs? So that anytime I make a graph with three different data lines, my top 3 preferred colours are the ones that appear before formatting? This would be very helpful and would save a lot of time considering in my company we like all the charts to have the same theme. Cutting out the process of changing the line colours each time would be great!

Thanks!
