This PR was merged into the 5.4 branch. Discussion ---------- [Console] Fix color support for TTY output | Q | A | ------------- | --- | Branch? | 5.4 | Bug fix? | yes | New feature? | no <!-- please update src/**/CHANGELOG.md files --> | Deprecations? | no <!-- please update UPGRADE-*.md and src/**/CHANGELOG.md files --> | Issues | Fix #53693 | License | MIT Prior to #53576, the output being a TTY was sufficient to consider the output as supporting colors. This is not enough but as a result, we are missing some additional checks. This PR: - Adds a check for the `COLORTERM` environment variable. From what I've found it does not look this variable is ever set if there is no color support. - Adds a check for the `screen-*` `TERM` values. Similar to the check we already for `xterm`, you have `screen-256color`, `screen-256color-bce`, `screen.xterm-256color` or more. Commits ------- 22efcd0 [Console] Fix color support

As reported in #53460, the modifications done in #52940 are incorrect as it results in detecting that the stream can support colors despite not being a TTY.
Rather than doing a simple revert which would re-introduce the pre-existing issue that #52940 attempted to fix, this PR checks if the output is a TTY based on Composer's code and does this check before anything else.
Indeed a TTY only means that colors may be supported, so the various checks that we were doing do make sense to be done but should be done after this TTY (so
Hyperis not an exception, it can be a TTY or not).
