I have coded up a perlin noise generator and can''t figure out how I would make the data into a RGBA image with colors that blend based on the value that the noise generator assigns? Thanks

Your noise generator will give you a different value for each input you give it. Your X,Y position on the map is the input. Your output is what to use for the colour. If you want 3 or 4 different values - eg. for red, green, and blue - try modifying the input somehow - by multiplying by a large prime number or something.
