does the light change colors or is it only blue?

Yes, it has various colors. Absolutely great machine. Haven't regretted the purchase for a single minute.

The light isn't blue at all--it starts out red and gets gradually brighter/whiter but it's always a warm toned light.

Mine is blue.. and I believe it's a blue LED with a white filter. Gives it a soft blue look.

There is a button on the bottom that allows u to change colors. That will hold the light at the color u desire if you don't want it to change Great lights

When it first lights up it looks like all one color but then they all start changing. It is like a rotation of color.Each will be a different color. It is really pretty.

It does change colors! It can cycle through pretty much every color. You can set it to cycle through colors, stay on one of those colors, or turn the light off.

It changes colors and modes just by hitting your light button . It works great

The light is blue. I haven't had any problems with them not working. In fact, my shipper sent extra batteries for when mine wore out and I haven't used any of them yet.

The colors don't "change." It just shines red, green, and purple. The lights does rotate.

It projects bright white light, even though the bulb is blue...magic.... the light mine put off does not look blue at all.

The light(when it works) is a bluish-purple, but it works because it emits ultraviolet light. Pure UV is invisible to the naked eye.

No, the transition goes between all colors, and no, the strobe is only white...

it has red, blue and purple. each at three different levels of brightness or off. it is bright enough to see easily, yet not too bright as to be a distraction.

You can switch the colors, a light version and a dark version of each, by just repeatedly clicking the same button. There is a strong white and a pale white light :)

It is temperature controlled. The light is blue when its cold green when warm and red is....(of course) hot.

Just one blue light that is lit when the hub is turned on. You can turn the hub off if need be.

It has 4 LED's in each color (red, green, blue) and at most will have 8 LED's on at once. So for example, while the 4 red LED's are on, the 4 blue LED's will start to fade up, those 8 will be on for a moment (color is now purple), and then the 4 reds fade away to make blue. It's pretty bright - we can use it with the bathroom lights off. Probably isn't bright enough to read by though :)
