Hi Juice and welcome to the forum.
Temps and humidity - The fluctuations in the temp and humidity are likely due to the change in bulbs and the changes with the AC. See if you can find a steady schedule. 90'F is definitely way too high. I shoot for a goal of 78'F during the day. Humidity can range between 70-80%. If you have a dimmer on the light dome, try turning it down a bit. I'm sure it will help both situations of high heat and low humidity.
Keeping in humidity - You can also cover half or more of the screen top with foil, Saran Wrap, glass, or plexiglass to help keep the humidity in. Adding plants helps too because the water droplets tend to cling to the plants giving you more surface area to hold the moisture.
Water - Be sure that you only use spring water or dechlorinated tap water for his soaking bowl and to moisten his substrate. Change water bowl water daily. Distilled water is fine for misting but when they soak in it it actually pulls electrolytes out of the frog through his skin because distilled water has no minerals or electrolytes in it.
The dark color...
Red eyed tree frogs and other tree frogs turn different shades for a few reasons...
Camouflage - you will find they they tend to blend into their environments such as lighter green when on light green leaves and darker green when in shadows. They also tend to turn a darker green at night especially when hunting for food. This is a normal response. Mine vary from a nice bright lime green, to a medium green, to a dark green and when under the florescent light they sometimes even look a little minty to almost slightly light blueish hue. They can even have separate portions of light and dark on them at the same time if half of them is in the lighted area and half in a shadowed area.
Infection - They should never have light green or brown slimy-looking spots. That is generally bacterial and/or fungal infection.
Stress - They often turn dark colors or stay darker colors when they are stressed or are not feeling well.
This could be do to any number of things.... environment or housing changes, interruptions by loud areas or areas of too much traffic and disturbance, improper temps and humidity (husbandry), uncleanliness of their homes, improper food items and poor nutritional choices, too large of prey, lack of gut-loading for food choices that lack nutritive value (crickets), lack of or too much supplementation of vitamins or calcium/D3, lack of feeling safe/secure in their homes, over handling of the frogs, improper housing set-ups such as terrestrial tanks for tree frogs and vice versa, lack of shelter areas such as trees for tree frogs and hides/caves for land-swelling frogs, lack of swimming areas for aquatic frogs, not keeping a usual day / night Lighting schedule, etc. I'm sure I've forgotten to list a few.
The goal is to provide the most accurate homes to their natural habitat, keeping it safe, providing security, minimizing stress by loud, crazy environments, maintaining proper cleanliness, and by proving them with the best nutrition.
Birthmarks - Scattered white slightly raised dots can be normal for them if they are already present on the frog and do not disappear or randomly appear. They are similar to a birthmark.

Monitoring color changes - The goal is to monitor any color changes and behaviors of the frog. Is he acting differently? Eating? Pooping? Peeing? Bloated? thin? Soaking? Has his energy level changed, ie is he lethargic? These are good indicators as to if things are okay or not.
If your frog is acting normally, eating, pooping, peeing, soaking, awake at night and asleep during the day, and the colors return to normal there is no cause for alarm.
The praying mantis as food - this is a good question and one I do not know the answer to. Do they eat them in nature...possibly. I would have to do some research. Are mantis's toxic? I do not know. You could shoot a PM to JeffreH. He is very knowledgeable in insects.
I hope this helps. Please ask more questions if I've missed anything.
Do you have a photo of your frog and his home?
