Though I also like Mathilde (the name of my host sister when I was an exchange student in France) -- the dark blue of the added "h" ultimately tries to extinguish the redness of the other letters for me, and the effect is less bold for me.
I am more of a blue-name type person if that makes sense. Nadine is baby blue to me. Matilda I can see in red. Never really thought about coloring names before, but I think it makes sense.
