256-color usage
Set the foreground or background color
color.C256(val uint8, isBg ...bool) Color256
c := color.C256(132)
c.Println("message")
c.Printf("format %s", "message")
c := color.C256(132, true)
c.Println("message")
c.Printf("format %s", "message")
Use a 256-color style
Can be used to set foreground and background colors at the same time.
color.S256(fgAndBg ...uint8) *Style256
s := color.S256(32, 203)
s.Println("message")
s.Printf("format %s", "message")
Run demo: go run ./_examples/color256.go
Use RGB color
Set the foreground or background color
color.RGB(r, g, b uint8, isBg ...bool) RGBColor
c := color.RGB(30,144,255)
c.Println("message")
c.Printf("format %s", "message")
c := color.RGB(30,144,255, true)
c.Println("message")
c.Printf("format %s", "message")
Create a style from an hexadecimal color string:
color.HEX(hex string, isBg ...bool) RGBColor
c := HEX("ccc")
c.Println("message")
c.Printf("format %s", "message")
c = HEX("aabbcc", true)
c.Println("message")
c.Printf("format %s", "message")
Use a RGB color style
Can be used to set the foreground and background colors at the same time.
color.NewRGBStyle(fg RGBColor, bg ...RGBColor) *RGBStyle
s := NewRGBStyle(RGB(20, 144, 234), RGB(234, 78, 23))
s.Println("message")
s.Printf("format %s", "message")
Create a style from an hexadecimal color string:
color.HEXStyle(fg string, bg ...string) *RGBStyle
s := HEXStyle("11aa23", "eee")
s.Println("message")
s.Printf("format %s", "message")
