See example.

Custom Patterns

Ways to specify the linetype:

• list, defining the pattern of dashes and gaps used to draw the line: [dash, gap, ...];

• list with specified offset: [offset, [dash, gap, ...]];

• string of an even number (up to eight) of hexadecimal digits which give the lengths in consecutive positions in the string.

See example.

Color and Fill

Colors can be specified using named colors, theme-dependent system colors ("pen", "paper", "brush"), RGB/RGBA strings, HEX values, or color(...). Named colors are case-insensitive; hyphens and underscores are ignored, and grey is treated the same as gray ("dark_orange", "light-blue", and "DARK-GREY" are valid). In addition to the named colors listed in the Named colors reference, grayscale names from "gray0" to "gray100" are supported. Transparency can be included directly in the color value by using an alpha-enabled format or by appending opacity to a named color, for example "steelblue / 0.35".

Type	Format	Example
Named color	name	"steelblue"
Named color with opacity	name / a	"steelblue / 0.35"
System color	pen, brush, paper	"pen"
RGB	rgb(r, g, b)	"rgb(70, 130, 180)"
RGBA	rgba(r, g, b, a)	"rgba(70, 130, 180, 0.35)"
Color function	color(r, g, b)	"color(70, 130, 180)"
Color function with opacity	color(r, g, b, a)	"color(70, 130, 180, 0.35)"
HEX RGB	#RRGGBB, #RGB	"#4682B4", "#48B"
HEX RGBA	#RRGGBBAA, #RGBA	"#4682B459", "#48B6"
Transparent	transparent, blank, empty string	"transparent"

For opacity values, 0 means fully transparent and 1 means fully opaque; percentage values such as "steelblue/35%" are not supported. See also an example.

System colors "pen", "paper", and "brush" can be used when you want a color to adapt to the active theme or flavor.

See example.
