I did some looking into this and there are some technical problems that make this difficult to implement. In theory, all that would need to be done would be to override the show() method for click.ClickException by either subclassing ClickException or by monkeypatching the class itself. However, when this method it called it is impossible to get the current click.Context with click.get_current_context(), which is needed to see if the color parameter is False.

Potentially, it might be possible for HelpColorsCommand to somehow hold on to the necessary Context, but I need to do more research into the problem.

I've managed to solve the problem by calling get_current_context() in the __init__() method of the exception.

I would be willing to implement colored errors and submit a PR.
