ShadersGLSL, HLSL and WGSL vectors in both encoded and linear form.

GLSL vec3 — sRGB	`vec3(1.0, 0.0, 0.431)`Encoded values. Use when writing straight to the framebuffer.
GLSL vec3 — linear	`vec3(1.0, 0.0, 0.156)`Light-linear values. Use for lighting, blending and mixing.
GLSL vec4 — sRGB	`vec4(1.0, 0.0, 0.431, 1.0)`
GLSL vec4 — linear	`vec4(1.0, 0.0, 0.156, 1.0)`

Engines & appsConstructors for Unity, Unreal, Godot, Flutter, SwiftUI and Android.

Unity Color	`new Color(1.0f, 0.0f, 0.431f, 1.0f)`Color for everyday scripting (0–1). Color32 when you need whole numbers from 0 to 255.
Unity Color32	`new Color32(255, 0, 110, 255)`
Unreal FLinearColor	`FLinearColor(1.0f, 0.0f, 0.1559f, 1.0f)`FLinearColor for materials and lighting. FColor when you need whole numbers from 0 to 255.
Unreal FColor	`FColor(255, 0, 110, 255)`Whole numbers from 0 to 255 — use when an API asks for FColor, not FLinearColor.
Godot Color	`Color(1, 0, 0.431, 1)`
Flutter Color	`Color(0xFFFF006E)`Packed ARGB, so alpha comes first.
Android Color	`Color.rgb(255, 0, 110)`
SwiftUI Color	`Color(red: 1, green: 0, blue: 0.431)`
UIKit UIColor	`UIColor(red: 1, green: 0, blue: 0.431, alpha: 1)`

Raw valuesPacked integers and plain arrays.

0x hex	`0xFF006E`
0x hex (ARGB)	`0xFFFF006E`

Array 0–255	`[255, 0, 110]`
Decimal integer	`16711790`

Contrast and accessibility

WCAG 2 ratios are what audits and legislation reference. APCA is shown alongside because WCAG 2 is known to misjudge mid-tone backgrounds, and it is the basis of the WCAG 3 draft.

Pairing	WCAG 2 ratio	Level	APCA	Suitable for
Winter Sky on white	3.83:1	AA Large	Lc 63	Headings and large text
Winter Sky on black	5.48:1	AA	Lc 39	Non-text elements only
