The colour selection simply isn't that great if you ask me. I wish there was a turquiose, light blue, or aqua blue colour. I would definitely have gone with a lighter blue if I had the choice.
There were three top colours when I got the FRS. Whiteout, Ultramarine, and Firestorm. But overall, I really wanted Ultramarine over the other two. Sometimes, I regret not getting whiteout. But I'm still very satisfied with the blue.
I chose Ultamarine because I've never owned a blue car before. Plus, after looking through all the color compliations on this forum, the Ultramarine is the colour that struck me most. White was a very close second but the reason why I didn't go with whiteout is because I already have a white MR2

it'd be boring to have two white cars. I didn't go with red because I've owned many red cars in the past. As well, red cries out "look at me!" too much and I wanted something a bit more low key. I love the firestorm, maybe if I was 21 years-old. But it's a bit too much attention for me.
So, the blue hit all the right buttons for me... I do wish sometimes I got whiteout though

I still love the blue though and have gotten many compliments on the colour. Especially from the guys at the dealer when I bought the car. And for whatever reason, it's more rare than the other colours. After selling these cars for one year, I was the only Ultramarine blue to go through the dealership I bought at!
