Since the tolerance band is brown, you only need to worry about which end to start reading from for resistor values that start with 1. If you have some 2% values, then you'd also need to worry about values starting with 2.The blue ones are just impossible to read, 1 because the contrast is very bad between colors and 2 because the very different coloring system they have for 5bands, than the classic easy to remember coloring 4bands and 3 because the lines are absolutly equaly distanced and you will have no idea where is the head and where is the tail of the color bands reading.
