[New] Added `set-colors` command. See details below:

This command allows users to replace default colors with their own custom colors. - top-level commands modified: alias, ls, ls-remote - helper functions added: nvm_echo_with_colors, nvm_err_with_colors, nvm_set_colors, nvm_get_colors, nvm_print_color_code - functions modified: nvm_print_formatted_alias, nvm_print_versions, nvm_print_alias_path (implicitly), nvm_print_default_alias (implicitly), nvm_list_aliases (implicitly) We added tests and info on using this command to the README!

+### Setting Custom Colors
+
+You can set five colors that will be used to display version and alias information. These colors replace the default colors.
+  Initial colors are: g b y r e
+
+  Color codes:
+
+    r/R = red / bold red
+
+    g/G = green / bold green
+
+    b/B = blue / bold blue
+
+    c/C = cyan / bold cyan
+
+    m/M = magenta / bold magenta
+
+    y/Y = yellow / bold yellow
+
+    k/K = black / bold black
+
+    e/W = light grey / white
+
+```sh
+nvm set-colors rgBcm
+```
+
+#### Persisting custom colors
+
+If you want the custom colors to persist after terminating the shell, export the NVM_COLORS variable in your shell profile. For example, if you want to use cyan, magenta, green, bold red and bold yellow, add the following line:
+
+```sh
+export NVM_COLORS='cmgRY'
+```
+
 #### Suppressing colorized output

-`nvm ls`, `nvm ls-remote` and `nvm alias` usually produce colorized output. You can disable colors with the `--no-colors` option (or by setting the environment variable `TERM=dumb`):
+`nvm help (or -h or --help)`, `nvm ls`, `nvm ls-remote` and `nvm alias` usually produce colorized output. You can disable colors with the `--no-colors` option (or by setting the environment variable `TERM=dumb`):

 ```sh
 nvm ls --no-colors
+nvm help --no-colors
 TERM=dumb nvm ls
