Solid Neon Blue background details
With hex #1F51FF (rgb(31, 81, 255)), this versatile mid-tone blue tone sits around 227° on the color wheel. Its bold, saturated color makes it feel focused and trustworthy, which is why designers reach for neon blue when they need a dependable background that still has personality.
Neon Blue, borrowed from glowing signs
Straight from signage: Neon Blue takes its cue from gas-tube lettering, and at #1F51FF it keeps the electric edge, bluer and harder than royal blue with just enough red to hum violet at the fringes. This is the blue of arcade marquees, synthwave album art, and rain-slicked storefronts after dark.
The color needs darkness to do its trick. Against black or near-black it appears to emit light, which makes it a natural for OLED wallpapers, gaming setups, and nightlife promotion. On white it loses the glow and becomes merely a loud blue, so build around shadow and let it burn.
A palette that works with Neon Blue
Matte black is the darkness Neon Blue glows against, and neon pink, cyan, and dark purple complete the standard synthwave signage kit.
