I think the thing with names and colours is people don't often think of the same colours with the same names.
Matilda sounds mauve-raspberry to you but to me it's really dark green, almost black. To me,
Jethro is pale yellow.
Susannah is sandy yellow-orange,
Benjamin is terra cotta...
Emmeline is blue,
Maeve is deep navy,
Tamsin is orange, red and gold.
Sylvia and
Sophia are a shimmering, pearly white.
Just saying, cos if you do use these names you gotta think that people really don't see the same colours when they hear them..
But using
Matilda cos you're descended of
Matilda is cool :)
