Data Types: char | string

Value — Color of document element

"black" (default) | character vector | string scalar | 1-by-3 array of doubles

Color of the document element, specified as one of these formats.

Format	Value
CSS color name	CSS color name. For a list of CSS color names, see https://www.w3.org/wiki/CSS/Properties/color/keywords.
Hexadecimal RGB value	RGB color in the format "#RRGGBB". Use # as the first character and two-digit hexadecimal numbers for the red, green, and blue values. You can use uppercase or lowercase letters.
Decimal RGB color value	RGB color in the format "rgb(r,g,b)", where r, g, and b are nonnegative integers that specify the red, green, and blue values, respectively. Each value range must be between 0 and 255.
Decimal percent RGB color value	Row vector of three nonnegative numerical values between 0 and 1. The first, second, and third elements of the vector represent the red, green, and blue values, respectively.

Example: "red" specifies a red color by using the CSS color name.

Example: "#0000ff" specifies a blue color by using the hexadecimal RGB value.

Example: "rgb(255,255,0)" specifies a yellow color by using the decimal RGB color value.

Method	Purpose
isValid	Use this method to check if a string is a valid color. tf = mlreportgen.dom.Color.isValid("red"); tf = logical 1

import mlreportgen.dom.*;
