Color.TryParseHexString

Parameters

Returns

bool Returns true if the operation was successful.

Description

Converts a hexadecimal string into a color.

String can be in one of the following formats:
#RGB (becomes RRGGBB)
#RRGGBB
#RGBA (becomes RRGGBBAA)
#RRGGBBAA

Note:
The '#' is optional.
Strings that are too short will be padded where rgb colors will be padded with 0 and alpha will be given full opacity(255). For example 'F' would become 'F00000FF' or 'AABBC' would become 'AABBC0FF'.


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