You don’t need any paid software, cracked utilities, or shady “RGB controllers” to change the color on your NOS keyboard. The vast majority of NOS keyboards support on-the-fly color switching using key combinations. Start with FN + F8 or FN + F7 – that solves 80% of cases. If not, try the alternate combos listed above. For advanced users, OpenRGB offers a free, safe way to unlock full color control, provided your NOS model has true RGB LEDs.
If none of the methods work, check your purchase listing: a “rainbow backlit” keyboard cannot turn solid blue. But for true RGB NOS models, these free methods will have you customizing your setup in under 30 seconds. Happy glowing.

These require no purchase or subscription.
