Yellow is indeed way too cute and shippable. Alias (N), Granted (Lance), Viridian (Silver), Amber (Gold), Jade (Blue female), etc. As for probably the most obvious ship for her,Special (Red), I'm neutral on it.
Spe!Gold and Blue female are also pretty shippable just because of their nature.
I guess Ruby, to very little extents because I like both MagmaJewel (Marge/Courtney) and Ralts (Wally). Maybe even Eyewear (Gold), too, to an even lesser extent. Frantic (Sapphire) will always by far be the owner of my heart, though, as my OTP.
