COLOR - How to choose a color? There is an international guide for color selection. It is commonly referred to as the J.L. Color Code. The numbers you'll find listed are standard throughout the hair goods industry. This color code is only a guide. Dye lots differ which causes variations in the shades, especially with the lighter colors. Colors also have different tones. For example, a brown can have red tones or golden tones. A color ring may be purchased and used for reference. Be sure to mention that you chose your selection of color from this ring as dye lots may vary from texture to texture. Note: Not all textures are available in all colors, so check desired texture for availability.
