Quoted: I would normally tell you to use "Aluminum Black" from Brownells but since it's a Colt and grey it probably wouldn't match.

I've used Aluminum Black on several rifles and they always match the original finish. The reason is the compisition of each upper is what makes the different shades.
You'll need: 90% or + Rubbing Alcohol, one small bottle of Alumunum Black, 1 Qtip and 2 minutes. Clean the Area free of dirt, grease, carbin and oil using the Alcohol. Dip the Qtip in the Aluminum black and Dab a drop onto the spot where the ding is. Allow it to sit for 2 minutes. Whipe off any left on there. Repeat if necessary although probably not. Use a damp paper towl or Qtip and clean the area with tap water then dry it using a soft cloth to "Polish" the area. Now apply gun oil to the area.
If you have a VERY FINE steel wool, carefully clean the scratch to remove any oxidation prior to applying the Aluminum black but this would only need to be done if the ding has been there for a long time. Oxidation of the Aluminum will cause it to have a "green tint" to the black color after you "die" it. If this happens you can simply re-do your repair by using steel wool on the ding then re-apply the Aluminum Black although it's better to remove oxidation first.
I restored an entire Upper & Lower and have enough left to do 8 or 10 more rifles from one small bottle. You can order the Aluminum Black from Cabelas, DCMP and Bushmaster just to name a few places. It is so easy to use and works fantastic.
Let us know how it comes out.
