Hello, It's me again. I'm getting close to the right temps in both my snakes habitats. I was worried that they were too hot and it turns out that they are not even close according to my new heat gun. I was terrified that they were too hot and it turned out they were very cold. I have the heating pad up all the way and it's still not there. I want to add a lamp that will give more heat but I need two pieces of information. What wattage should I get and what color should I get? I understand that snakes see some colors and it kind of concerns me that it would irritate them with some. Should I have two bulbs with different colors to simulate day and night? Should the temps vary at all between day and night?

Thank you for your help in advance.
