Hue vs Hue curves are great until the client asks you to match last week's spot. Then you're eyeballing bezier handles.

Six Vectors gives you numbers.

R · Y · G · C · B · M, each with:

• Hue ±30°
• Sat 0–2×
• Lum ±1 stop

Why it's clean

• Smooth falloff with adjustable Vector Width (30–120°)
• Overlaps blend, they don't stack
• Neutrals are protected automatically, so your whites stay white
• Hue rotates around the neutral axis, so luminance holds
• Isolate any vector to see exactly what you're touching

Grade one shot. Copy the node. The numbers travel. Works on log (DWG / ACEScct) or Rec.709 nodes.

Olive greens. Teal skies. Deeper reds. Done before the client finishes their coffee.
