The first thing I did was to update my\u00a0Homer Simpson Duff Beer Watch<\/a>\u00a0to take advantage of the new selector.<\/p>\n As you might know this watch face not only consists of one changeable color but two: One for the background and one for the hands.<\/p>\n The solution is the shader<\/a> HSV<\/strong>. You can change the color’s hue, saturation and value based on the set color for the element.<\/p>\n With the help of the hue value<\/strong>\u00a0of the shader you can define\u00a0a different color in the spectral color circle in relation to the selected base color (i.e. {ucolor}).<\/p>\n Of course you should\u00a0play around with the other properties of the HSV shader as well. The following diagram shows you the principle of HSV and you can get more information<\/a> on wikipedia.<\/p>\n The hue value of the shader is restricted to the additive color mode<\/a>\u00a0of spectral light.\u00a0Because of that, you can’t use<\/strong>\u00a0the concept of traditional<\/strong>\u00a0complementary colors<\/em><\/a>. They are based on the subtractive color mode<\/a>. If you’d like to use this kind of concept, you have to write (or find) a conversion lua script function for that.<\/p>\n If you don’t care<\/strong> about the traditional\u00a0complementary colors you can of course use the RGB complementary colors<\/em><\/strong> by using the hue value of “50”<\/em><\/strong>.<\/p>\n You can also use the RGB shader<\/em> to limit or boost the primary color share of the selected {ucolor}. Unfortunately you can’t combine shaders for one and the same element.<\/p>\n You can always control the “V” (color value) of HSV by using a grey scale for the bitmap images. You can read more about coloring bitmap images in this article:\u00a0Color changing<\/a>.<\/p>\n For privacy save likes click 2 times.
