Text based arrow recommendations

I'm doing a visual that is going to display some arrows as a quick guide. Ideally i'd love to dynamically change the font colour on the arrows but that doesn't appear to be an option, so instead i'll go with ASCII/UNICODE arrows.  First ones i've tried are a little hard to see, so i figured i ask what arrows are your favourites?


Here is my example:

These are Unicodes: 8657, 8663, 8660, 8664, 8659
