* **Automatic color extension**

  Enter the number of results to be expanded, that is, the number of expanded color systems. The algorithm calculates the uniform sampling method according to the color space, and gives the results that meet the requirements of the number of expanded colors. Simply put, the number of color systems is how many, and a few pictures are output.

  For example, 【Before processing】【`color_count`=`1`】【`color_count`=`4`】. The result is as follows:

  ![Image](https://img.ailabtools.com/rapidapi/ColourMigration/processed-auto-splicing-3.jpg)

* **Color palette extension**

  Input a set of color lists (color swatches), and the algorithm uses the swatches as the main color to expand the original image. This mode provides greater color control. The length of the color list must not exceed the specified value.

  For example, 【`color_template`="#DB0D0D,#0E0CBB,#FF0000"】. The color extension result is as follows:

| Before processing                                                                         | After processing                                                                                  |

* **Reference picture extension color**

  You provide a reference image, and the algorithm will colorize the original image based on the reference image.

| Before processing                                                                         | Reference map                                                                                     | After processing                                                                                 |
