I like the BOLDNESS. I also like the use of the circle shape... but don't love its application 100%.
I really like the 3 colors... "and" could be a tiny bit more subtle and ".com" could be a bit bigger.
I am lost about the lines - looks like a UPC symbol - I still want something a bit more iconic. Maybe Arrows of hot and cold, or something like the circle shape - something?
Thank you for your comments and suggestions. I want to describe the heat with cool red and blue combined with a thermometer. Maybe I'll try the logo as you wish.
