Tim,
My ERA just left CT Custom.  I had ordered about 3 different blues and 4 different whites from automotivetouchup.com and painted them, with stripes, on business cards.  I put them on my dash and looked at them every day going to work.  Here's what I picked:
Toyota/Lexus Indigo Ink Pearl 8P4 - PPG 5775
GM White Diamond Pearl GBN - PPG 5851
I liked the way the Indigo was very dark on one angle and transitioned to a medium blue at another angle.

If you have an ERA and want to be listed, contact me with your info and I'll put it up.  The minimum info I need is chassis number and location.  The rest is up to you.  The most information needed would be: chassis number, body type, city, name, CC nickname, and email address.
