How do I get the hex color from an RGB color?

I am reading an image and getting its colors in RGB via image/color. However, I want to convert a color to hex triplet. How do I do this?

img, err := jpeg.Decode(someImg)
color := img.At(x, y) # I would like to convert this from RGB to hex

Hex is just hexadecimal representation of RGB values you can simply do something like

fmt.Printf("#%02x%02x%02x", R, G, B)
