[Pharo-dev] Morph should not query Color for nil :(

[stepharo]

Morph>>colorString: aColor
    aColor ifNil: [ ^'nil' ].
    ^aColor name
        ifNil: [ aColor storeString ]
        ifNotNil: [ :colorName | 'Color ', colorName ]

such behavior should be moved to Color.

The problem is not Morphic per se. This is that OO design was often not 
considered.
