Its red red red
Black is never the first band of a resistor color code, so you must be reading the stripes backwards. Orange-Orange-Black = 33 ohms.
It's the tolerance of the resistor - +/- 10% (grey), 5% (tan/orange), 2% (red), 1% (dark red/maroon), etc.
2 red 2 red 2 zeros=red red,red,red that's assuming you meant 2.2K
The first three bands on a resistor tell you what its resistance is. The first band is the first digit, the second band is the second digit, and the third band is the number of zeros to add. Use the resistor color code to convert... 0 Black 1 Brown 2 Red 3 Orange 4 Yellow 5 Green 6 Blue 7 Violet 8 Grey 9 White As an example, a 27000 ohm resistor would be Red - Violet - Orange. If the third band is Silver, the multiplier is 0.1 and, if the third band is Gold, the multiplier is 0.01. For example, a 0.39 ohm resistor would be Orange - Gray - Gold.
if a diode has color band markings they are on the cathode end
A megohm is 1,000,000 ohms, so 2.2 megohms is 2,200,000 ohms, often abbreviated to 2.2M, or 2.2Mohm, or 2M2.
First off, it's going to have a brown and an orange ring for the first two bands but then your last band is going to depend on the tolerance of the resistor whether it's +/- %.05 up to +/- %10.

The values and colours of the bands are as follows (0) Black (1) Brown (2) Red (3) Orange (4) Yellow (5) Green (6) Blue (7) Violet (8) Grey (9) White The first two bands are the value, the third is the multiplier (times ten). So as an example if the first band is Red, the second is Green, and the third is Orange, the value would be 25000 or 25k Ohms.
On a standard four band resistor: yellow, violet, black, and gold.
Orange, although that's what I think ;)
