Was outside for approx 3.5 hrs and saw an object flashing red/green and later white moving slow,fast,up/down,left to right and visversa

It was the 1st time I've ever seen something like this.I honestly saw this object moving from left to right and right to left at slow speed,super fast speed, and stationary. For the 1st 1.5 hours it was flashing colors and then flashing only white for the next 1.5 hours. I was measuring it's movements using the peak of my neighbors roof and have to say I was amazed. It's hard to say what the distance was that it covered but was not much using my measuring method. I would say that it's movements were in pretty much in a small area and always in the west. I believe it was also moving up and down and down and up and at times the movements were so so fast that it stunned me. I was texting my family explaining what I was seeing and also called channel 27 news to report it. The guy I talked to told me to email photos but I told him my camera on my phone was absolutely terrible. I did take a few pictures but they were 100% black. To make a long story short I don't believe it was a satellite and I know it was not a planet or a star. I really want to know if anyone else saw this strange object as I did. If possible can you let me know?? If more info is needed please contact me. Thank you!
