Among the color samples, a light color sample expressing a light color tone occupies a larger space than samples expressing the other color tones. A deep color sample expressing a deep color tone in the color card is arranged on one side of the light color sample, and a neutral color sample expressing a neutral color tone which stands between the light and deep color tones is arranged on the other side. Use of such a color card allows the user to roughly select a color card showing a color tone suited for being applied to an object to be painted from a plurality of color cards based on their light color samples, and then select one of color tones shown in the selected color card.
