A simple application used to count number of Hama/Nabbi/Ikea Pyssla beads necessary for recreating an image.
Download it from my blog page
Launch the application, click load to select your image and click count to get a list of colors (Hex format) and how many bead are needed per color. Note: the counting includes background beads, if the same color is used for both background and front colors, you may want to edit the image in your favorite editor and change background color.
