is blue light from led so bad cause it’s harder to make blue leds and thus the color range is more limited than red and green for what a blue light produces and thus causes our brains to get confused

No. Blue LEDs are used with a cover to create full spectrum white light. Bluer light makes our brain think it’s day time and can inhibit sleep.
