Well its not the preferred tan-brown burn, but there is no oil problem...However on the electrode....I have never seen a orange color on the electrode.....Are you using an addative?

The cause is the octane booster you added. Unless you're running high compression (~10.5 points or more) you really don't need the stuff, etc. It is questionable whether it does anything at all.
Unlikely it caused any damage other than making your plugs look funny. Additives can mess with oxygen sensors in modern cars, but not most of ours.
Should be able to clean those up and reuse them if you want.

This is definitely what plugs look like from using octane booster. Sends them orange. Light brown/orange deposits encrusted on the ground and/or center electrodes indicate ash deposits.
The fuel additives can add to the ash (octane booster) could be part of your problem.
However see how it appears to be concentrated more on one side. I dont want to raise any type of alarm but often when deposits are found on only one side of the spark plug core nose, it is usually considered to be a problem with the cylinder head (valve stem seals or valve guides) where it is concentrated most. When they are found on both sides of the spark plug, it is often considered to be a problem sealing at the piston rings.
Dont jump to conclusions. Clean them up or fit a new set. No octane booster or other fuel additives. Give it a good run & pop a couple of plugs from the cylinders you noticed were the most effected ones & see how they shape up.
