Drug info - Ketamine colored yellow???

[PowerTrips]

greetings all,

SWIM recently purchased 1.4 grams of K powder from a dope dealer
who cuts dope wit it. I'm almost certain it was definitely K because
of the way the powder looked (u know how a small bump or line
kinda looks like a half moon n it was a very fine powder). But the powder was yellow n I snorted it over three sessions (first time I was on 8mg alprazolam n half a bottle of cough syrup wit codeine. ya'll know bout tha "Sizzrup"? second time I was just drunk. third time I was sober) n at no one time did it ever work. is there any other powders that look just like K?? is there such a thing as yellow K? anyone have any opinions on this??
