How do Professional Killstreaks work?

I'm going to buy a Strange, Professional Killstreak weapon.

I have a sever where it lets you farm kills, I want to use it for the strange quality, I can get to 5000 kills in 30 minutes with the server.

I know that professional killstreak makes your weapon glow for the certain killstreak count 5-20, Red, Blue, Pink, Orange, Yellow, Bright Green, Subdued Green, and Purple but...

My question is: is the glowing effect permanent for each stage, and will it stay like that? If I farm on the server, and get 1000 kills, will I completely bypass the other colors, and go straight to purple really quickly, and won't be able to get the other previous colors EVER, or does it reset every time I join a new server. And does it go with the same thing with particle effect to the user's eyes?

Reason for this question, I want to see the different colors, but I also want to get to Hale's own 5000 kills on the strange.

The sheen colors glow regardless of how many kills you have, in addition it does not change colors depending on how many kills you get. With Professional kits you get the following effects which are visible on the user's eyes once you reach a killsteak milestone.

The list of effects are:

Cerebral Discharge
Fire Horns
Flames
Hypno-Beam
Incinerator
Singularity
Tornado
