Silk Naturals

the colors i thought of when you were listing what you were looking for were nectar and rhapsody.
nectar is my favorite SN lippie. i don't think of tender as a cool color, but nectar is a little 'warmer'--more red/brown, but sooo pretty. on my lips tender is very sheer and it just gives them that little pinky brown shimmer, just like the description.
rhapsody is also browner and has more coverage since it is a black label, but is still somewhat sheer. it's a reddish plum brown.
rare berry would be too bright for what you are looking for, and i think pout would be too cool if tender is cool on you. i don't have sweetheart so i can't say about that one. breathless is nice--neutral pink with good coverage (almost like a lipstick).
as far as a "berry" for you--i'm not sure what to recommend. berry nice is certainly a dark berry color, but it has no brown or shimmer--just a dark stain (i really like the non-shimmer kisser slicker formula though). figment is a nice plum color, but also has pink. it's warmed up by a copper shimmer.
hope that all doesn't make it more confusing--if i were you, i'd definitely try nectar!!

Thank you for all the suggestions ladies!

The lovely lwoodall10 was generous and sent me some samples to try. I found lippies that work for me have some brown in them. My lips tend to absorb brown pigment, like with Nectar... my lips were left with a nice sheer red stain and no trace of brown. If I applied it heavily, it was a bit much, but applied lightly, it is very nice... so thank you for suggesting Nectar Is Jaybird similar to Nectar?

What you ladies think of Breathless, Rhasphody, Birthday Suit and Skinny Dip?

I think Breathless may pink up on you too much, but I think the rest of them will probably work. I think they will have enough brown to counteract the pink in your lips.

Copper Rose (wand gloss) would probably look really good on you, too.
