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

GLSL vec3 — sRGB	`vec3(0.0, 0.502, 0.0)`Encoded values. Use when writing straight to the framebuffer.
GLSL vec3 — linear	`vec3(0.0, 0.216, 0.0)`Light-linear values. Use for lighting, blending and mixing.
GLSL vec4 — sRGB	`vec4(0.0, 0.502, 0.0, 1.0)`
GLSL vec4 — linear	`vec4(0.0, 0.216, 0.0, 1.0)`

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

Unity Color	`new Color(0.0f, 0.502f, 0.0f, 1.0f)`Color for everyday scripting (0–1). Color32 when you need whole numbers from 0 to 255.
Unity Color32	`new Color32(0, 128, 0, 255)`
Unreal FLinearColor	`FLinearColor(0.0f, 0.2159f, 0.0f, 1.0f)`FLinearColor for materials and lighting. FColor when you need whole numbers from 0 to 255.
Unreal FColor	`FColor(0, 128, 0, 255)`Whole numbers from 0 to 255 — use when an API asks for FColor, not FLinearColor.
Godot Color	`Color(0, 0.502, 0, 1)`
Flutter Color	`Color(0xFF008000)`Packed ARGB, so alpha comes first.
Android Color	`Color.rgb(0, 128, 0)`
SwiftUI Color	`Color(red: 0, green: 0.502, blue: 0)`
UIKit UIColor	`UIColor(red: 0, green: 0.502, blue: 0, alpha: 1)`

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
Green on white	5.14:1	AA	Lc 75	Headings and large text
Green on black	4.09:1	AA Large	Lc 27	Not usable for text
