The R is the most important aspect of the Robin costume to me. Each one is distinct (minus Jason) and fits with the individual. Dick has a solid, bold R that is prominent and on display in bright yellow with a black contrast that helps make it pop. Tim's R is probably the most recognizable, it's the stylized R that is too big for it's background, I see it as Tim stepping into the role not knowing how to fill the void left after Jason's death. Tim's needs to have that same color contrast with a yellow R and black background, it feels more like a homage rather than a conscious decision for "style" like Dick's.
