Red Red Black Orange Brown — 220 kΩ

Read left to right, starting from the end where the bands are grouped. The brown band is the tolerance and always sits alone at the far end. Five bands means three significant digits — this is a precision part.

If you misread one band

Brown and red, or orange and red, are easy to confuse under a desk lamp. These are the codes one band away from this one.
