Credit

In addition to the Go standard library, this program also uses the following modules. Many thanks to their authors.

• github.com/marekm4/color-extractor finds the primary color of images and tiles.
• The KNN implementation from github.com/cdipaolo/goml finds the closest match for a tile color.
• github.com/disintegration/imaging handles all the image resizing.

For the example image:

• The Go Gopher was designed by Renee French
• Base image by Takuya Ueda
• Tile images were gathered from around the internet, but mainly the Go blog
