Anyone know if the HF Origins colors are different from the GMK Hyperfuse colors?
Yes, they are different.
HF Origins is meant to replicate the "Origins" of the set, which initially was released through Signature Plastics.
So the alphas are not white like in GMK HyperFuse R1 or R2... they are grey.
The light accents are a vibrant mint, not cyan. The modifier grey is slightly changed as well.
See below.
