What steps will reproduce the bug?

$ FORCE_COLOR=1 NO_COLOR=1 node -p 1 1 (node:69290) Warning: The 'NO_COLOR' env is ignored due to the 'FORCE_COLOR' env being set. (Use `node --trace-warnings ...` to show where the warning was created) $ node -h | grep COLOR NODE_DISABLE_COLORS set to 1 to disable colors in the REPL

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior?

Expect node -h to mention that node responds in some way to the NO_COLOR and FORCE_COLOR environment variables.

Documentation specifies that FORCE_COLOR and NO_COLOR can be used to simulate a different color depth terminal, but should identify the logic by which one or the other is preferred, and stipulate that a warning will be generated if both are set.

What do you see instead?

No mention of FORCE_COLOR and NO_COLOR environment variables.

Only limited mention in docs.

Additional information

Handling of NO_COLOR and FORCE_COLOR were added in 273398a3d09, however the documentation does not mention that node will warn if both are set, only that they can be used to simulate a different color depth support level.
