What color is represented in the range of 90-99?

The range of 90-99 is typically associated with the color gold, especially in contexts where numerical scoring or grading systems are used. Gold is often used to symbolize high achievement or excellence, which aligns with this numeric range indicative of top performance. In various grading systems, for instance, a score in this range represents exceptional results, making gold a fitting representative color.

In contrast, other colors listed such as green, blue, and white don't carry the same connotation of high achievement within this particular numeric system. Green might signify progress or approval in different contexts, blue could denote calmness or reliability, and white often represents purity or neutrality, none of which specifically denote the concept of excellence that gold encapsulates within the 90-99 range. Thus, gold is the most appropriate answer in this scenario.
