A birthday illustration with the wrong shade of pink. A wedding drawing where the florals are lavender instead of dusty rose. These seem like small things until the client sees them and feels the drawing is not actually theirs.
Generic festive palettes are not the same as event-specific ones
Freelancers sometimes default to what reads as celebratory in a broad sense: bright golds, saturated reds, classic white and blush. But every event has its own specific colour story, and clients notice when yours does not match theirs.
I once submitted a New Year celebration piece using a standard gold and navy palette. The client had done their entire event in champagne and sage green. Technically beautiful, completely wrong.
Building the right reference habit
Request the event colour palette as part of your standard brief. Ask for photos of invitations, decor swatches, or a mood board. If the client does not have one, ask them to send three images that capture the feeling they want.
Match your palette to those references before you start, not after the sketch is approved.
Colour is where clients feel seen or overlooked. Get it right early and the rest of the revision process gets much easier.
