Problem with ortho-imagery conversion

Hello Group,
I'm a newbie, please bear with me.
I've read what I can find on combining monochrome image layers. I've followed instructions to layer images using Overlay Control Center. My final images have good green and blue areas, but with small areas of bright purple.
Here's what I get from my downloaded files:
GeoTiff, Universal Transverse Mercator (UTM), Zone 10
Band 1 (Blue-green), 30 metres (19,078 KB) [ http | ftp ]
Band 2 (Green), 30 metres (18,605 KB) [ http | ftp ]
Band 3 (Red), 30 metres (20,129 KB) [ http | ftp ]
Band 4 (Near Infrared), 30 metres (23,868 KB) [ http | ftp ]
Band 5 (Mid Infrared I), 30 metres (22,629 KB) [ http | ftp ]
Band 6H (Thermal Infrared, high gain), 60 metres (4,344 KB) [ http | ftp ]
Band 6L (Thermal Infrared, low gain), 60 metres (3,385 KB) [ http | ftp ]
Band 7 (Mid Infrared II), 30 metres (20,898 KB) [ http | ftp ]
Bands 743 (Short-wave Infrared Composite), 30 metres (68,358 KB) [ http | ftp ]
Band 8 (Panchromatic), 15 metres (85,373 KB) [ http | ftp ]
I'm using bands 1-3, and Blend mode Keep blue, green, and red, respectively.
Not getting a good result.
Any input would be appreciated.
Thanks,

Paul,
Can you save a workspace file with your setup so that I can take a look and perhaps provide the actual links to the data in case I need to look at that?
Thanks,
Mike
