Article: While natural worms are pinkish or brownish in color, most fishermen favor non-natural worm colors, with purple being the most popular. In general, anglers fishing plastic worms follow the same rule as fishing other lures, using light colors such as blue, green, or pearl on bright days and clear water conditions and darker colors such as purple or black on dark days and in cloudier or choppy water.  Some worms, notably the ripple-tail variety, feature 2 colors, usually a darker color for the head and a lighter, sometimes fluorescent color, for the tail. The fluorescent tail color can be an attractor in particularly dark water conditions.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/0\/08\/Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet1.jpg\/v4-460px-Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet1.jpg","bigUrl":"\/images\/thumb\/0\/08\/Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet1.jpg\/aid2007031-v4-728px-Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Some plastic worms are impregnated with flecks of glitter to give them a metallic appearance.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/3\/3a\/Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet2.jpg\/v4-460px-Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet2.jpg","bigUrl":"\/images\/thumb\/3\/3a\/Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet2.jpg\/aid2007031-v4-728px-Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  In some cases, when the fish are nibbling on a plastic worm but not hitting solidly, you can increase your chances of success by changing to a different color worm, even if the new color doesn't follow the "light day-light color, dark day-dark color" rule.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/0\/00\/Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet3.jpg\/v4-460px-Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet3.jpg","bigUrl":"\/images\/thumb\/0\/00\/Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet3.jpg\/aid2007031-v4-728px-Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-2Bullet3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"} Use shorter worms with light tackle in clear water or clear sky conditions when the fish aren't biting, such as during the first few days following a cold front. Use longer worms when fish are biting aggressively. In most cases, you'll favor a length of 6 to 7 inches (15 to 17.5 cm). If you're fishing for smallmouth bass, choose a shorter worm; if you're fishing for largemouth (particularly the larger Florida strain), choose a longer worm.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/4\/46\/Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-3Bullet1.jpg\/v4-460px-Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-3Bullet1.jpg","bigUrl":"\/images\/thumb\/4\/46\/Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-3Bullet1.jpg\/aid2007031-v4-728px-Rig-a-Fishing-Pole-for-Plastic-Worm-Fishing-Step-3Bullet1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}
