Color digital images allow for the use of tools such as Photoshop
and Pantone Matching Systen for electronic part identification
Resitors
Color Bands identified with high degree of reliability on RGB grids
Where part is in shadow, Use of Photoshop to adjust color balance
so part may still be identified
Capacitors
Heat shrink colors vary by manufacturer A sprague blue is different than a Cornell-Dublier
If part is identified it may rule out a certain capacitance value
Sprague may might not offer a 0.053mfd, therefore that cap<val>not in circuit
Wiring
Aside from conventions regarding positive, negative, ground
color coding may indicate its intended use
Inductors
Determine spool or inductor length
Air core or iron
Determine wire gauge
Determine packing fraction Random, factory or careful overlay
Determine thickness of winding
Cross sectional area of winding times packing fraction (.907) divided by cross sectional area of 1 strand of wire equals number of windings
sigma layers( each layer increased in radius by constant amount)
Calculate length of wire, inductance
Stienhaus packing fraction for factory winging is .907
