to honestly answer the OP's question, i would say the only colors that will be "trippiest" for you will be the colors that have strong emotional associations to YOU.
for example, my maiden psych voyage was on fresh psilocybes in seattle. so I have my fondest memories of powerful trips at night in autumn in seattle. the clear cold purple sky, the bright yellow streetlights, the deep green trees, the beautifully patterned (crayola sometimes!) brick buildings and walkways...
the colors that you surround yourself with can really change your mood. i'm not sure if i believe in new-age crystal/energy stuff, but i'm pretty sure that colors are like anything that we can tie memories to-- like the smell of mom's home cooking, or the sound of your best friend's bark.
