尝试通过 bash 脚本显示不同的颜色

Question

我是脚本编写的新手，并决定通过我给自己布置的作业来学习。
这个脚本的目标很简单：

在颜色中显示可用颜色
选择一个数字来复制颜色方案的十六进制颜色值。

除 Black0~3 和 Gray0 外，所有颜色都正确显示。
这 5 个选项显示为青色和绿色。（请查看截图）
尝试谷歌搜索但无济于事。任何帮助将不胜感激。
提前致谢。
（我不知道这个信息是否有帮助，但是 OS: Linux, Terminal Emualtor: ST, Shell: zsh）

#!/bin/sh

# grab hex code
function fromhex() {
  hex=
  if [[ $hex == "#"* ]]; then
    hex=$(echo  | awk '{print substr([=11=],2)}')
  fi
  r=$(printf '0x%0.2s' "$hex")
  g=$(printf '0x%0.2s' ${hex#??})
  b=$(printf '0x%0.2s' ${hex#????})
  echo -e `printf "%03d" "$(((r<75?0:(r-35)/40)*6*6+(g<75?0:(g-35)/40)*6+(b<75?0:(b-35)/40)+16))"`
}

Answer 1

看看这个gist。

您可以将其调用为

colors --256

并检查您想要的黑色和灰色值，然后将映射函数设置为 return。

Answer 2

由于您使用的是支持真彩色的现代终端，因此您可以直接使用十六进制颜色：

function fromhex() {
  hex=${1#\#}
  r="0x${hex:0:2}"
  g="0x${hex:2:2}"
  b="0x${hex:4:2}"
  printf '\x1b[38;2;%d;%d;%dm' "$r" "$g" "$b"
}

并将 $(tput setaf $<color>) 替换为 ${<color>} (sed -E 's/$$tput setaf $([^)]*)$/${}/g)。
