Patterns are (always) your friends:

<xs:simpleType name="colorList">
       <xs:restriction base="xs:string">
        <xs:pattern value="(R|r)(E|e)(D|d)"/>
        <xs:pattern value="(Y|y)(E|e)(L|l){2}(O|o)(W|w)"/>
        <xs:pattern value="(G|g)(R|r)(E|e){2}(N|n)"/>
       </xs:restriction>
</xs:simpleType>

That's still verbose, but less than adding all the combinations!

(E|e)(R|r)(I|i)(C|c)

PS: why xs:string and not xs:token?
