Method and apparatus for realizing color tween animation

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• displaying, on a display of a computing device, a start fill scheme in a first layer that is initially non-transparent;
• displaying, on the display, an end fill scheme in a different second layer that overlaps the first layer and is initially at least partially transparent;
• and
• gradually changing a first transparency value of the first layer to a value corresponding to transparency, and gradually changing a second transparency of the second layer to a value corresponding to non-transparency, wherein both the first transparency value and the second transparency value are gradually changed during a particular time period, and wherein gradually changing the first transparency value and the second transparency value includes changing the values by a plurality of increments over the particular time period.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• displaying, on a display of a computing device, a start fill scheme in a first layer that is initially non-transparent;
• displaying, on the display, an end fill scheme in a different second layer that overlaps the first layer and is initially at least partially transparent;
• and
• gradually changing a first transparency value of the first layer to a value corresponding to transparency, and gradually changing a second transparency of the second layer to a value corresponding to non-transparency, wherein both the first transparency value and the second transparency value are gradually changed during a particular time period, and wherein gradually changing the first transparency value and the second transparency value includes changing the values by a plurality of increments over the particular time period.
