Attempting first project - Some questions if I may

Caution: the color is NOT yellow, it is orange.
Your camera flash and slight overexposure have turned orange yellowish.

It must be orange because orange orange brown silver is a standard value:
330 ohms 10% tolerance.
Yellow yellow brown silver would be 440 ohms 10%, which is not at all a standard value.

Resistors cannot be substituted with any higher resistance value. The substitute should be within the tolerance specified by the 4th band. For example, you could use 330 ohm 5% in place of 330 ohm 10%.

A resistor of a higher wattage may be substituted, that is you could replace a half watt by a one watt of the same resistance and tolerance.
