描述

With #3739 fixed, it'd be a good idea to give users a better error message/prompt when the use new color() (as if color is a class) rather than color(), because color() operates like a cast ala int() and float().

研究方向
First, refer to the fix mentioned in issue #3739 to understand the current color() behavior. Then, locate the source file(s) where color() is defined (likely in the core library). Look for how parsing or function calls are handled, and add a check that detects when users write 'new color()' and provide a helpful error message suggesting to use 'color()' instead. This should be a simple string addition in an error handler. No other files need modification.
