Seems like it is long forgotten about the use of blending colors ONLY at the CRT pixel level as a form of "FOR YOUR EYES ONLY". Such visual sleigh of working "stegography" code whose name has eluded me to date. Its code is quite easily recreateable today but the diminishing supply of RGB-based CRT monitors has rendered this mode of stealthy delivery of info rather obsolete. This approach does not use least-bit of an element of RGB for hidden data stream but more about neighboring RGB pixels creating a separate color particularly on the CRT screen in which to "draw" a picture or set of words. The higher resolution of today's LCD monitor has now eluded our eye's perceptual resolution (although I could imagine someone getting up super close to a LCD screen to get such color-infused "messages". Would escape nearly all stego detectors today due to lack of deep matrix (RGB mixing), no?
