Create an image with a black background, in outer space but with bursts of light

Create an image with a black background, in outer space but with bursts of light or fire, of calm golden colors, blue and lilac, with emphasis on lilac. I want very little gold and blue. Make something that looks really interesting in the footer background of a web developer's website. Make everything elegant and modern. I want a more neon gold, some tone related to fiber optic cable light. I want everything to look like it's floating. I want the floor as if it were a computer motherboard, dark plate
