The most common is the <strong>4-band color code<\/strong>, which consists of:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>First band<\/strong>: first digit<\/li>\n\n\n\n<li><strong>Second band<\/strong>: second digit<\/li>\n\n\n\n<li><strong>Third band<\/strong>: multiplier (power of ten)<\/li>\n\n\n\n<li><strong>Fourth band<\/strong>: tolerance<\/li>\n<\/ol>\n\n\n\n<p>Each color corresponds to a number:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Black = 0<\/li>\n\n\n\n<li>Brown = 1<\/li>\n\n\n\n<li>Red = 2<\/li>\n\n\n\n<li>Orange = 3<\/li>\n\n\n\n<li>Yellow = 4<\/li>\n\n\n\n<li>Green = 5<\/li>\n\n\n\n<li>Blue = 6<\/li>\n\n\n\n<li>Violet = 7<\/li>\n\n\n\n<li>Gray = 8<\/li>\n\n\n\n<li>White = 9<\/li>\n<\/ul>\n\n\n\n<p>Multipliers are 10 raised to the number represented by the third color. Tolerance is shown by the fourth band:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Gold = \u00b15%<\/li>\n\n\n\n<li>Silver = \u00b110%<\/li>\n\n\n\n<li>No band = \u00b120%<\/li>\n<\/ul>\n\n\n\n<p><strong>a.
