Why does blue seem to be the hardest color to achieve for so many things, such as LEDs, fireworks, and paints or dyes?

What makes blue special? Also what category would this be?

Not an answer but blue is the shortest wavelength and therefore the highest energy of the visible spectrum. And higher energy is harder all around to deal with. For example, 7,000 kelvin light bulbs emit a lot of blue spectrum and many people find them to be burning and fatiguing of their vision. Another example is radio engineering, where higher frequencies are orders of magnitude more difficult to design and have increasingly erratic behavior. So it is built in to the wavelength/frequency of the light wave and the amount of energy required to generate it.
