@SWinxy Yes, only because the result is publicly exposed : `stringToColor` is also used by `javax.swing.text.html.StyleSheet stringToColor` method to publicly return the `Color` Object. It seems unique, I didn't see any other usages.

I saw these methods but in our case we need a result anyway. Using `containsKey(Object)` implies a second request to get the value ?
