Overview
When using the designer, you need to modify the color attribute frequently, such as adding a background color to a cell, modifying the font color, and modifying the series color for a chart.
In such cases, you can use the color function. Open the color panel where you can select a required color from default colors in Theme Color, Standard Color, or Recently Used. If the default colors cannot satisfy your needs, you can also click More Colors to customize the color as needed, as shown in the following figure.
Color Panel
The following figure shows the color panel.
You can pick a required color directly in Custom. Three methods are available for color picking.
1. You can click the color palette to pick a color. The corresponding color values will be displayed on the right of the color palette after you pick the color.
2. You can enter the values of RGB or HSB, or the standard hexadecimal color code to pick the color, and the color will be displayed on the color palette.
RGB, one of the most widely used color system, is a color model that constructs all the colors from the combination of the red (R), green (G) and blue (B) colors, which includes almost all the colors human can perceive.
HSB (HSV) is a color model that defines a color using three attributes: hue (H), saturation (S), and brightness (B).

Hexadecimal Color Code: A method of specifying a color using a six-digit code usually preceded by the pound (#) symbol. The six digits are divided into three parts. The first two digits tell you how much red is in the color, the next two digits are for green, and the last two are for blue.
You can check out color-related readings to learn more about color.
3. You can pick a color by the eyedropper. Click the eyedropper, move the cursor to the specified position of the color you want, and click to pick the required color.
After selecting the color, you can see the effect of the selected color in the preview area, as shown in the following figure.
In addition, you can pick the color from colors set by default in Sample directly.
