  • Named Colors
    When you select a color swatch on this tab, its color name and hexadecimal RGB code appear in the Color field. When you select a Basic or Additional named color, an attribute:colorname pair is inserted into your CSS style definition.

    For example, while editing an HTML page in Design view, select the <BODY> element in the Document Outline window and choose Build Style from the Format menu.

  • System Colors
    When you select a color, a system color category appears in the Color field and an attribute:category pair will be inserted into your CSS style definition when you close the Style Builder dialog box.

    For example, while editing a CSS style sheet, place the cursor between the braces ({ }) of a CSS style for the <BODY> element and choose Build Style from the Format menu. Select Background and choose the ellipsis button (...) next to the Color field to open the Color Picker dialog box. On its System Colors tab, select the Background color category, and choose OK. When you close the Style Builder dialog box, the following attribute:colorname pair will be inserted into your BODY style:

    BODY { BACKGROUND-COLOR: background; }

    Note

    When you use a system color, you are not specifying the color to be displayed. The background color varies from system to system, depending on which desktop color the user has chosen. In general, you should use System Color categories only on Web projects designed for groups of users who share common and predictable Display settings.

    For more information, see System Colors Tab, Color Picker Dialog Box.

  • Custom Colors
    To create a custom color, drag the sliders for the primary colors red, green, and blue until the desired hue appears in the Preview field. Its RGB color code, displayed in the Color field, will be inserted into your CSS style definition when you close the Style Builder dialog box. The decimal values displayed to the right of each slider range from 0 (no color) to 255 (maximum color); the default value for each is 255.

    Note

    A custom color is displayed using your monitor's current Display settings. It can look different in another user's monitor and Web browser. You might wish to reserve custom colors for use on Web projects designed for groups of users who share common and predictable Display settings.

    For example, while editing a CSS style sheet, place the cursor between the braces ({ }) of a CSS style for an INPUT.button style class, select Background in the Build Style dialog box, and then choose the ellipsis button (...) next to the Color field to open the Color Picker dialog box. On its Custom Color tab, leave the Red and Green sliders set at their default values of 255, and drag the Blue slider left to 102. When you close the Style Builder dialog box, the following attribute:RGBcolor pair will be inserted between the braces ({ }) of your style:

    INPUT.button { background-color: #ffff66; }

    For more information, see Custom Color Tab, Color Picker Dialog Box.
