Irish reds often have some munich malt, a fair amount of crystal, and a tiny bit of roasted barley or black patent to bump up the caolor. Use an online recipe calculator like brewtoad to estimate your color before brewing.
Crystal 50 or higher but as you go higher, watch your levels. Carastan too. Small ammounts of roasted barley help improve the color to make a more crimson red, rather than amber red.
I've also used about 4-5 oz of Roasted Barley for a 5 gal batch. I'm actually also adding about 12oz of Rye malt to an Irish Red recipe this Sunday to give it a red boost. Plus I want a wee bit of Rye flavor in it.
