The main difference between Dodger Blue and Royal Blue is brightness and saturation: both are blue shades, but they share similar brightness and Dodger Blue is more saturated. Dodger Blue (#1E90FF) is a bright sky-blue named after the Brooklyn Dodgers, while Royal Blue (#4169E1) is a deeper, richer medium blue. Dodger is lighter and more cyan; royal is darker and slightly purple-leaning.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Dodger Blue is more saturated (100% HSL vs 73%) so it reads as bolder and more memorable at logo scale, while Royal Blue can feel washed out when printed small.
Royal Blue hits a 4.85:1 WCAG contrast against white — safer for text-heavy interfaces — where Dodger Blue only reaches 3.24:1 and risks failing AA at small body sizes.
Royal Blue is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Dodger Blue leans cooler and is better suited to autumn/winter layering.
Royal Blue is the more muted of the two (73% saturation) and sits more calmly on large wall surfaces, while Dodger Blue's higher chroma can overwhelm a room when used beyond accent pieces.
Dodger Blue (RGB 30,144,255) is a bright, saturated blue leaning toward cyan — named after the Brooklyn/Los Angeles Dodgers baseball team. Added to CSS3 as a named color.

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.
