Exactly. In particular with the ROTY, they have the same arrangement (or colorblocking) of color (red on the Chis but wheat on the ROTY), black, and white, as the Chicagos. And since the Chis are one of the OGs, that colorblocking is deemed the Chi colorblocking. The Reverse SBB also share this colorblocking. The Blk/Reds and Royals have the same colorblocking in terms of their color, black, and white arrangement, and we all just call that Blk/Red colorblocking. We include the Shadows as having the same colorblocking, even though they are technically different in that they have a black outsole, as opposed to a colored (Shadow) outsole like the other two. The other common colorblocking people reference are the SBB/colored toe (see SBB OG, Pine Toe, Court Purple Toe, Blk/Red Toe) and the Black Toe (with the white toe, white tongue).
