Questions about Pokeblocks and feeders in RSE?

This Bulbapedia articlementions “single-color Pokeblocks”, which I don’t understand because I thought each Pokeblock has exactly one color. How can a Pokeblock not be single-color? Or is it supposed to say “single-flavor Pokeblocks”?

Also, the article says that if I use a feeder to encounter a Pokemon, and I throw a Pokeblock that’s the same color as the one in the feeder, then the wild Pokemon might not be enthralled. How is this possible?

The less-likely-wrong strategy:

Make three different colors of single-flavor Pokéblocks (e.g., Red, Blue, and Green). Put one into a feeder (e.g., Red) and start a wild encounter near that feeder.When the battle starts…

If the Pokémon’s catch rate is higher than 200, throw Safari Balls;Else, throw a Pokéblock with a taste different from the one in the feeder (e.g., Blue).If the Pokémon is curious (escape factor = 0), throw Safari Balls.If the Pokémon ignores the Pokéblock, throw a Pokéblock with the same color as the one in the feeder (e.g., Red).If the Pokémon is enthralled (escape factor = 0), throw Safari Balls.If the Pokémon is enthralled, then…If it has a catch rate between 165 and 200, throw Safari Balls.If it has a catch rate below 165, throw a Pokéblock with the third color (e.g., Green).If the Pokémon ignored the Pokéblock, then throw Safari Balls.If the Pokémon is curious, throw the same Pokéblock again (e.g., Green) (escape factor = 0), then throw Safari Balls.
