colors/mod.ts: brightBlue looks more like magenta

Describe the bug

Using the color std module. If you want to output brightBlue the output txt looks (almost) like magenta. bgBlue, bgBrightBlue, blue work ok

Steps to Reproduce

console.log("brightBlue", brightBlue("brightBlue"));

Expected behavior

The output should look like (bright) blue

Environment

• OS: macOS Ventura 13.1
• deno version: 1.29.1 (release, aarch64-apple-darwin)
• std version: 0.164.0

This is a valid behavior then. Based on your output, this is exactly how it should look for xterm, see: https://en.wikipedia.org/wiki/ANSI_escape_code#3-bit_and_4-bit You can either change your term to screen-256color which will give you a different set of colors, or modify settings of your terminal emulator to update color codes for the one you want. This is a user-specific configuration and escape codes are standardized, so there’s nothing we can change here tbh.

I think @kamilogorek has done a pretty good job explaining why this is pretty much unactionable.

Unless @sspilleman has a proposal for what can be done, I think this issue should be closed as an issue with terminal.app and not with the deno std.
