Describe the problem

In the Arduino IDE 1.x output panel, content received from the standard error stream (AKA "stderr") is colored differently (with the default theme, in red) than output received from the standard output stream ("stdout"). This makes the output easier to read, and highlights the content which may indicate a problem.

Arduino IDE 2.x displays all output in the same color, which makes it more difficult to read, and easier for the user to miss important content.

This for example is how it looks like in the 1.8.9 IDE (left) and the 2.0.0 IDE (right) with both the same errors
