Configuration

hexyl colors can be configured via environment variables. The variables used are as follows:

• HEXYL_COLOR_ASCII_PRINTABLE: Any non-whitespace printable ASCII character
• HEXYL_COLOR_ASCII_WHITESPACE: Whitespace such as space or newline (only visible in middle panel with byte values)
• HEXYL_COLOR_ASCII_OTHER: Any other ASCII character (< 0x80) besides null
• HEXYL_COLOR_NULL: The null byte (0x00)
• HEXYL_COLOR_NONASCII: Any non-ASCII byte (> 0x7F)
• HEXYL_COLOR_OFFSET: The lefthand file offset

The colors can be any of the 8 standard terminal colors: black, blue, cyan, green, magenta, red, yellow and white. The "bright" variants are also supported (e.g., bright blue). Additionally, you can use the RGB hex format, #abcdef. For example, HEXYL_COLOR_ASCII_PRINTABLE=blue HEXYL_COLOR_ASCII_WHITESPACE="bright green" HEXYL_COLOR_ASCII_OTHER="#ff7f99".
