Line color options
Here you can specify how the line painted over the image will look like. You can also add up to 6 colors to your color palette.
In the Line color options click on +Add to add a new line to your palette. You can change lines colors by inserting the color code into the Line color field. The acceptable formats are: "rgb (255, 0, 0)", "rgba (255, 0, 0, 0.8)", "#FFFFFF", "white". An RGB color value is specified with: rgb(red, green, blue). Each parameter (red, green, and blue) defines the intensity of the color and can be an integer between 0 and 255 or a percentage value (from 0% to 100%).
RGBA color values are an extension of RGB color values with an alpha channel - which specifies the opacity of the object. An RGBA color value is specified with: rgba(red, green, blue, alpha). The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).
You can also set lines width in pixels in the Line width (px) field. This can be found under More Options.
