First Day of Summer

Bright daylight yellow-green, calmer than Beekeeper
About First Day of Summer
I keep thinking of morning light on pale leaves, that yellow-green edge where the brightness feels soft instead of loud. First Day of Summer sits lighter than Beekeeper and Cornflake, but it doesn't drift into the yolk-cream warmth of Cheesy Frittata. The undertone is greener and cooler, so it reads airier and more "spring-filtered" rather than dairy-gold.
Use it when you want a bright background that still behaves like a base. I've used it for ag-tech landing pages, field-monitoring dashboards, and eco logistics screens where the UI needs clarity without turning into a warning label. It also works in food media for header bands and side rails, especially alongside forest greens, sage, and restrained olive tones. Warmer than cream but cooler than straight yellow, it holds its shape better when the layout has lots of white space.
Quick note: on very dark surfaces it can lose a little of that green cast, so plan your contrast and pair it with deeper greens or warm grays to keep the mood clean, not washed.
