GSK Color Codes
GSK works in an orange, hex #F36633, with a deep purple, hex #40003C. The GSK color codes in Hex, RGB and CMYK can be found below. GlaxoSmithKline was assembled in 2000 from Glaxo Wellcome and SmithKline Beecham, brands that trace back to a New Zealand dried-milk business and a Victorian pills maker; in 2022 it shortened its name to GSK and spun its consumer health lines off as Haleon. Its nearest peer on this site is AstraZeneca.

What the GSK Logo Colors Mean?
The GSK logo colors were chosen in 2022 to look less like a legacy pharma company. Orange is rare in the sector and reads as energetic; the aubergine purple behind it keeps the pairing from turning into a consumer-goods look. The redesign came with the name being cut from GlaxoSmithKline to three letters.
GSK Logo Color History
GSK logo color history has one sharp break. From 2000 the identity was a blue-and-orange interlocking mark; the 2022 rebrand kept an orange but pushed it warmer, added the purple, and dropped the old symbol for a plain wordmark.
GSK Logo Fonts
GSK logo fonts are a custom bold sans with rounded corners. A geometric face such as Poppins is the nearest match.
GSK Logo JPG
GSK logo in JPG. No transparency, so it is flattened onto white. Safe for documents and slide decks.
GSK Logo PNG
GSK logo in PNG, with a transparent background. Use it over a colored surface.
GSK Logo WebP
GSK logo in WebP. Same transparency as the PNG at about a third of the file size.
GSK Color Code Shades
GSK color code shades step evenly from the primary toward black, for hover states, borders and shadows.
These are interface steps, not GSK paint or trim names.

Brand colors are chosen for recognition, not for legibility. A failing value here is normal. It means use it as a fill, not as text.
