BinImg = rand(100, 100) > 0.7;  % LOGICAL type

% Example 1: TRUE pixels are white, FALSE pixels are black:
RGB = double(cat(3, BinImg, BinImg, BinImg));

% Example 2: TRUE pixels are red, FALSE pixels are black:
RGB = double(BinImg);
RGB(end, end, 3) = 0;

% Example 3: TRUE pixels get green:
RGB = zeros(100, 100, 3);
RGB(:, :, 2) = BinImg;
