140x192 resolution in 16 color?



    I have read all Apple II family throughout websites.  Some claims that 
Apple //e has 560x192 resolution in monochrome and 140x192 resolution in 16 
colors.  I can't be certain to be correct.  I believe that 140x192 
resolution should be 6 colors.
    I did plot 16 colors in 140x192 resolution and 560x192 resolution 
according to my theory in DHGR, but HGR is always accurate.

In HGR
    Violet is in 0-1, 4-5, 8-9, etc positions of first 140x192 resolution.
    Blue is in 1-2, 5-6, 9-10, etc positions of second 140x192 resolution.
    Green is in 2-3, 6-7, 10-11, etc positions of third 140x192 resolution.
    Orange is in 3-4, 7-8, 11-12, etc positions of forth 140x192 resolution.

    Four 140x192 resolutions equal to 560x192.  They are normally 280x192 
resolution at 7MHz as Text and HGR.  Six colors are very restricted in each 
positions which some positions are unused or black.

    LGR and DHGR use 560x192 resolution at 14MHz.  Sixteen colors do not 
have restriction in each positions.  All positions are always shown 16 
colors.

In LGR and DHGR
    Both LGR and DHGR are identical, but LGR uses DHGR's 16 pixels.

    Red is in 0, 4, 8, etc position.
    Dark Blue is in 1, 5, 9, etc position.
    Dark Green is in 2, 6, 10, etc position.
    Brown is in 3, 7, 11, etc position.

    Light Blue and Dark Gray are in 0-2, 4-6, 8-10, etc position.
    Aquamarine and Light Gray is in 1-3, 5-7, 9-11, etc position.
    Pink is in 2-4, 6-8, 10-12, etc position.
    Yellow is in 3-5, 7-9, 11-13, etc position.

    White is in 0-3, 4-7, 8-11, etc positions.
