ColorUtility.TryParseHtmlString

Parameters

Returns

bool True if the string was successfully converted else false.

Description

Attempts to convert a html color string.

Strings that begin with '#' will be parsed as hexadecimal in the following way:
#RGB (becomes RRGGBB)
#RRGGBB
#RGBA (becomes RRGGBBAA)
#RRGGBBAA

When not specified alpha will default to FF.
Strings that do not begin with '#' will be parsed as literal colors, with the following supported:
red, cyan, blue, darkblue, lightblue, purple, yellow, lime, fuchsia, white, silver, grey, black, orange, brown, maroon, green, olive, navy, teal, aqua, magenta..

The following example creates a custom PropertyDrawer that allows the user to input html colors. This property drawer can be shown in the inspector when a color property has the attribute ColorHtmlProperty.
