You certainly did not try hard. It was simple to achieve, importantly -- without P/Invoke...

Solution 1

First of all, you absolutely don't need to use P/Invoke. It would kill platform compatibility. You can run the multi-colored console code which would run on many different platforms, such as Linux, Max OS X (for example, via Mono) — without recompilation. Usually, you can use 16 colors for both font background and foreground at the same time.

This article explains how. I tried it — it works. Please see:

Solution 2

No need to call kernel API. Simply set the desired color to Console.ForegroundColor property.
