在Go中使用color.RGBA结构类型创建新颜色时，出现错误，指出整数格式错误

Question

I am trying to create a color pallete using

var palette = []color.Color{color.RGBA{0xRR, 0xGG, 0xBB, 0xff},color.Black}

but I am getting this error:

./lissajous.go:13:40: malformed integer constant: 0x
./lissajous.go:13:42: malformed hex constant
./lissajous.go:13:42: syntax error: unexpected RR, expecting comma or }

Answer 1

Invalid value 0xRR, 0XGG in Original code. Not a number literal.

example is

palette := []color.Color{color.RGBA{255, 0, 0, 255}, color.Black}

color.RGBA type has uint8. so has valid values 0 <= C <= A.
