Hi Baldy82,
Welcome to the Toplace forum! You'll get a lot of great information here. The hair density in those photos is 65-70%. There is no straight body wave---it's either straight or body wave. Body wave is one step up from straight. Those units are probably body wave although it's difficult to be exact since they're relatively short and most of the wave ends up on the stylist's floor. As for color that's very difficult to tell from a computer monitor because of different settings. #1 is jet black and the darkest color you can get. Looks to me like like there is some brown in there but we recommend that you provide a hair sample---that's the best way to get the color right.
Regards,
John
