Question 1

How to use gookit/color to print error messages in red?

Accepted Answer

Use the built-in style color.Error.Println('message') for a standard error format, or for custom red text, use color.Red.Printf('Error: %s', msg). Both methods handle cross-platform output automatically.

Question 2

gookit/color vs chroma for Go terminal colors?

Accepted Answer

gookit/color is a general-purpose color library focused on cross-platform CLI output with zero dependencies, while chroma is specialized for syntax highlighting. Choose gookit/color for coloring log messages or UI text, and chroma for code highlighting in tools like linters.

Question 3

Does gookit/color work on Windows PowerShell?

Accepted Answer

Yes, it fully supports Windows PowerShell and CMD for 16, 256, and true RGB colors since version 1.2.4, with automatic detection to ensure colors render correctly without manual configuration.

Question 4

How to disable colors in gookit/color for CI environments?

Accepted Answer

Set the NO_COLOR environment variable, or call color.Disable() programmatically to turn off color rendering. This ensures compatibility with CI systems that may not support terminal colors.

Question 5

Can I use custom RGB colors with gookit/color?

Accepted Answer

Yes, use color.RGB(r,g,b) for RGB values or color.HEX('#RRGGBB') for hex codes. Example: color.RGB(255, 0, 0).Println('Custom red') creates and outputs true-color text.

Question 6

gookit/color performance impact on CLI tools?

Accepted Answer

It's lightweight for most use cases, but the HTML-like tag parsing can add overhead for high-frequency output. For typical CLI tools, the impact is negligible, but avoid tags in performance-critical loops.
