There are a number of ways to create a color palette for your Illustrator design projects, but if you’re looking for a harmonious palette based on two colors, the Blend Tool takes the cake! With the Blend tool, you can create two identical shapes filled with two different colors, then blend them with a set number of steps to mix new colors based on the two originals. The result? A harmonious swatch family to complement your next project!
To create new colors with the Blend tool, select the Rectangle or Ellipse tool from the Tools panel. Click and drag on the artboard to create a simple shape. Copy and paste the shape so you have two of the same shape. Fill each shape with one of each of the colors that you want to base the palette. Choose Object > Blend > Blend Options to display the Blend Options dialog box. Select Specified Steps from the Spacing pop-up menu, and then enter a number in the Spacing text box indicating how many different colored shapes you want Illustrator to create. A low number from 3-5 is ideal. Click OK.
Next, select the two shapes, choose Object > Blend > Make, and Illustrator will create the designated number of shapes, each with a different color mixed from the original two you started with! To add the colors to your Swatch panel, select the Eyedropper tool, click one of the swatches to make it the foreground color, click the options menu in the Swatches panel and select New Swatch. Finally, click OK in the New Swatch dialog box to add it to the panel. Repeat for each color.
