    You literally can’t make white LEDs without them. That includes all flat-screen display technology. After the development of blue and green LEDs, decades and untold money were spent trying to develop blue LEDs.

    The device you’re reading this message on is only possible because of Blue LEDs.

    Your issue isn’t with the blue LEDs - it’s with the atmosphere, which absorbs red and green light more quickly than blue. It’s why the sky appears blue. it’s also why white LEDs bulbs will often have a yellow filter on them to absorb some of the blue light. Because pure white appears blue-ish in hue.
