📜 Origin & History

Tele Gray 2 was born in the early 21st century with the popularization of LCD display technology. Unlike the pure black screen of a powered-off CRT TV, early LCD TVs presented a faintly glowing blue-gray when on standby, due to the technical reason that the backlight module couldn't be completely turned off even when dimmed to the darkest setting.

In the 2000s, the boot screens of almost all consumer electronic products used a blue-gray gradient background. From the Windows XP welcome screen to the PlayStation 2 startup animation, Tele Gray 2 defined the aesthetic tone of digital products in that era.

Apple's former design chief, Jonathan Ive, introduced Tele Gray 2 into the aluminum surface treatment of the MacBook. The blue-gray tone, finalized after dozens of anodizing experiments, gave the cold aluminum alloy a warm, skin-like touch.

In contemporary digital minimalist design, Tele Gray 2 is regarded as the ideal color for tech products to摆脱 (break free from) coldness. It has one more layer of breathing blue-green than pure gray, giving electronic devices more visual warmth, making them more approachable and touchable for users.
