Nokia took to packaging updates for Windows Phone and referring to them by a code name – Lumia “Black” being the last biggie for Windows Phone 8. The packages are a combination of operating system upgrades (that will be made available to all handset manufacturers) along with Nokia-specific upgrades, which may improve the way their handsets function, either in general or somtimes specific to the new OS version.
The much-awaited upgrade to Windows Phone 8.1 is now rolling out for Nokia users, combined with an array of tweaks, and is going under the name of Lumia Cyan.
Cyan isn’t a colour that the Man on the Clapham Omnibus is likely to have knowingly encountered, but Speccy geeks of all ages may have come across it either on their computer or as part of a CMYK printing process. Mixing colours to create other shades is as old as cave painting, but in the modern world there are essentially two processes – adding colours together in light (assuming you start in darkness), you could project blue, green and red in varying combinations to make all colours (where R+G+B is white), and in printing or dyeing colours and where the starting point is white, then the process of mixing a different set of primary colours – Cyan, Magenta, Yellow and Black – has the effect of absorbing light to leave the desired colour behind.
Anyway, for more information on the mondo-update that’s jazzing up the Lumia WP8 range, see Nokia’s Lumia Cyan website for more detail. The site also lets you check the global availability of Cyan (see here for Europe, then click on the main body of the page and press the END key to jump to the bottom if you’re a UK user), since it is rolling out by country, by handset model and by mobile carrier.
If your country/handset/carrier combo shows up as “Under Testing”, hold tight – it may take a few weeks to complete the process and make the update available for everyone. Check for updates by going into the phone settings | system | phone update.
UK users: you may need to wait for the first update to WP8.1 in order for Cortana to show up, unless you want to set your phone to be a US region handset. Or install the GDR1 preview by using the Preview for Developers program.
