I don´t have the palette, but I have seen in at the store, and I can tell you: there is DEFINITALY no dupe for the pink. There are similar LE shades like PLAYFUL, ROMPING - but the texture of this is absolutely the BEST of all pinks I know. PLAYFUL is quite similar, but much softer and more transparent - and a bit less bright.
The blue one, do you mean the darker one? I think something like DEEP TRUTH should match quite well...
