As you see in the picture, there are only 16 possible colors that the beacon can make on bedrock edition. But on Java and Console, it is FAR more than that. If you make a rainbow beacon the way I made in the picture on Bedrock, there are a short amount of colors made, but copy what I did on Java, it displays a wide rainbow of colors. Please try and fix this, I have been disappointed since 1.2 since beacons came out.
As you see, there are only seven colors in that rainbow. On java there would be over 21 colors in that rainbow. Please fix this. It bugs me a lot.
