The main difference between Deep Pink and Ruby is brightness and saturation: both are pink shades, but Deep Pink is lighter and Deep Pink is more saturated. Deep Pink (#FF1493) has an HSL of 328°, 100%, 54%, whereas Ruby (#E0115F) sits at 337°, 86%, 47%.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Deep Pink is more saturated (100% HSL vs 86%) so it reads as bolder and more memorable at logo scale, while Ruby can feel washed out when printed small.
Ruby hits a 4.76:1 WCAG contrast against white — safer for text-heavy interfaces — where Deep Pink only reaches 3.64:1 and risks failing AA at small body sizes.
Deep Pink is a warm tone that flatters spring/summer collections and warmer skin undertones, while Ruby leans warmer and is better suited to autumn/winter layering.
Ruby is the more muted of the two (86% saturation) and sits more calmly on large wall surfaces, while Deep Pink's higher chroma can overwhelm a room when used beyond accent pieces.

Text legibility depends on the contrast ratio between foreground and background. WCAG 2.1 AA requires at least 4.5:1 for normal text and 3:1 for large text; AAA requires 7:1. Use these numbers to choose accessible combinations for your design.
