ive seen everything in person. and too me, 5K and 6K is too white. 8K looks nice and 10K was kinda dark blue. i understand its harder to see and thats why i want the 8Ks. but i already have the 10Ks so if i dont like them, ill just get the 8Ks. 5K would be useless to buy because stock is already bright white...no point in wasting money like that
