Gold, Silver, and Bronze classification of members hard to distinguish

When the symbol of the Gold, Silver, or Bronze classification is shown on a member's website, the colors seem so similar that it's visually impossible to determine if a member has achieved either a Gold, Silver, Bronze classification.  In the past, at least when describing what these classifications meant, there were actual color symbols to compare with a member's symbols.  Either the colors need to be much more prominently distinguishable or examples need to be posted again.
