Graphical element color diffusion techniques

In a digital medium graphical element rendering environment, a system comprising:

• a graphical element input module implemented at least partially in hardware of a computing device to receive a character of text;
• a color diffusion replication module implemented at least partially in hardware of the computer device to, automatically and without user intervention:
• obtain color location data describing first, second, and third color locations and color identification data indicating respective colors associated with the first, second, and third color locations, respectively;
• map the color locations to the character of text;
• determine the first and second color locations are disposed within a boundary of the character of text and the third color location is not disposed within the boundary of the character of text;
• represent the first and second color locations as Steiner points;
• generate a mesh within the boundary of the character of text based on the Steiner points;
• diffuse the respective colors associated with the first and second color locations within the boundary of the character of text based on vertices of the mesh, the respective color of the third color location is not diffused within the boundary of the character of text;
• and
• a display module implemented at least partially in hardware of the computing device to generate, for display in a user interface, the character of text as live text having the diffused colors.

In a digital medium graphical element rendering environment, a method implemented by one or more processing devices, the method comprising:

• obtaining, by the one or more processing devices, color location data describing a plurality of color locations and color identification data indicating respective colors associated with the plurality of color locations;
• mapping, by the one or more processing devices, the plurality of color locations with respect to a character of text;
• determining, by the one or more processing devices, one or more color locations of the plurality of color locations are disposed within a boundary of the character of text and at least one color location of the plurality of color locations is disposed outside of the boundary of the character of text;
• representing, by the one or more processing devices, the one or more color locations as Steiner points;
• generating, by the one or more processing devices, a mesh within the boundary of the character of text based on the Steiner points;
• diffusing, by the one or more processing devices, the respective colors associated with the one or more color locations within the boundary of the character of text based on vertices of the mesh, the diffusing does not include the respective color associated with the at least one color location that is disposed outside of the boundary of the character of text;
• and
• generating, by the one or more processing devices for display in a user interface, the character of text as live text having the respective colors associated with the one or more color locations diffused within the boundary of the character of text.
