Match Sapphire Bot's
color.

Sapphire Bot is one of Toon Tone's 30 original robots. The fill color sits at hue 220°, saturation 90%, brightness 70% — a vivid blue that's easy to misjudge under cool screen lighting.

What makes this character matter for color training isn't just the hex value. It's the gap between what you remember after the preview and what your slider actually produces. That gap is what Delta-E measures, and Sapphire Bot is sized to make that gap visible without being punishing.

If you're working through the full roster in order, Sapphire Bot pairs well with the next character in its hue family — they share lighting cues but diverge on saturation. Use this one to build your color-memory baseline, then test it on the harder ones.
