(First post hope this is the right sub-forum)

I've just released an app that converts any image (from camera or gallery) to specific hardware palettes.
Conversion is based on colour distance taking into account perceived brightness. This might be usefull for the members here as it is quite accurate.

I'm not simulating specific resolutions because my first goal was to have something that could be used by non-experts.
But I'm sure it might be of interest to some of you.

To avoid any trademarks I'm using generic names for the palettes, but the colors are acurate:

• Monochrome, Amber and Green are based on early PC graphics as displayed on CRT monitors.

• LCD is inspired by the Game Boy handheld

• Col 80A and Col 80B are inspired by the ColecoVision and TRS-80 Color home computers

• CGA palettes cover most of the variations possible with the PC graphic cards, including custom modes. These palettes feature High and Low intensity variations.

• Fruit 77 is based on the Apple II

• TI9918 is based on the MSX and compatible computers.

• Com 80 approximates the Commodore VIC-20

• RGB 8 is inspired by Sinclair computers and Teletext.

• Com 64 is based on the Commodore 64

• CGA 16 colors uses the full CGA palette

• Fruit 87 approximates the Apple Macintosh

• PC 92 is based on the Windows 3.1 color palette.

• Friend 85 is inspired by the Amiga Workbench default colors.
