Value — Color of document element

character vector | string scalar | three comma-separated positive integers | row vector of three positive numerical values

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

Format	Data Type
CSS color name	Specify as a character vector or string scalar. The name must be a CSS color name. See https://www.w3.org/wiki/CSS/Properties/color/keywords.
Hexadecimal RGB value	Specified as a character vector or string scalar using the format #RRGGBB. Use # as the first character and two-digit hexadecimal numbers for the red, green, and blue values. You can use either uppercase or lowercase letters as part of a hexadecimal value.
Decimal RGB color value	Specify three comma-separated positive integers, values, in the string "rgb(values)". The digits specify the red, green, and blue values. Each value ranges from 0 to 255.
Decimal percent RGB color value	Specify a row vector of three positive numerical values. The digits specify the red, green, and blue values. Each value ranges from 0 to 1.

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

Example: "#0000ff" specifies a blue color using a hexadecimal RGB 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

Create a blue color object and apply it to a paragraph. Instead of specifying the CSS color name 'blue', you could use the hexadecimal value '#0000ff'.

import mlreportgen.dom.*;
doctype = 'html';
d = Document('test',doctype);

colorfulStyle = {Bold,Color('blue')};
p = Paragraph('deep sky blue paragraph');
p.Style = colorfulStyle;
