I've not played around with command blocks, but it's a bit more than redstone components. When Factorio items are wired together with signal cable they have a few different operating modes. You can specify what objects are requested from a delivery network and what items are taken from a chest, or if any are to be taken at all. So this solution involved chests being filled with various items that have a specific color on belts, and then staggering pulls from the chests to place on belts in such a manner as to make pixels. Those commands were issued by combinations of the constant signal block, the comparison/decider block, and the arithmetic block. I would say those entities are between NAND gates and pre fabricated if/else or for loop constructs.
