Color Mapper Now Listen To Me Geocacher

Color Mapper reads an image of a colored-square grid, samples the color at the center of each cell, and converts each square to a single letter using a fixed color→letter mapping (colors outside the standard palette get custom symbols). Handy for decoding color-grid geocaching puzzles. Load or paste your image, then nudge the Top / Left / Width / Height until the crosshairs sit in the centre of each block.

Adjust the grid

Adjust the top, left, width and height until the grid is in the center of the blocks. You can also use fractions. Rows and Columns are filled in automatically — or type a count yourself and the width/height is recalculated to fit the image. Alternatively use Pick grid corners above to click the top-left and bottom-right block centres; Rows and Columns then divide that selected area.
