Color Palettes A good starting point for choosing fl ower colors is to use one of the many color palettes, or selection tools, that have been developed over the years. Tools that can be used for this purpose include the 12-hue color wheel, the Munsell color system, and the Munsell color tree. Another color wheel, devised by Sir Isaac Newton, includes seven colors in order of their appearance in a rainbow. Today it takes the form of either a wheel or a color chart called ROYGBIV, which stands for Red-Orange-Yellow-Green-Blue-Indigo-Violet, see Figure 8-7. Several mnemonics, or memory devices, have been developed to help people remember the order of the colors. Some of the more popular ones include the following: • Roy G. Biv • Rinse Out Your Granny’s Boots In Vinegar • Richard Of York Gave Battle In Vain • Rowntree Of York Gave Best In Value • Read Out Your Good Book In Verse 7th Son Studio/Shutterstock.com Figure 8-6.
