I have the paint4models chart downloaded also, but it is easier to use if you just launch it each time
the downloaded chart makes us click on page after page to see all the matches, the Launch option lets you just look for anywhere from 1-10 (or your choice) paint ranges at a time
you can set if for FS number and name, and PolyScale number and name, for example,,,or you can set if for all fields, type in the last 4 digits of the FS number and only see all the various matches for that color
or you can search for the number in your model kit instructions, leaving off letters, etc,,,,,,,,and it will show all the paints that match H-55, for example, just by typing 55 in the search box and looking to the left and right of the Gunze H-55 result
the only warning is that the chart was made from "advertised color" meaning that since Vallejo says Model Color 952 Lemon Yellow is the same as FS x3655 Lemon Yellow, that is where it is on the chart,,,,,,,even though it is really 33793 paint in the bottle, and Vallejo's physical match for 13655 is really Model Air 71002 Yellow

edit to add: I forgot to say not to worry if you type in a color that starts in a 1, a 2 and a 3 and when you see the list there are slightly different colors and RGB codes for each line,,,,,,,,,,this is one of the charts that "got it right" and the lines are supposed to be different colors for each sheen,,,,,,,the only other option is that the guy somehow "created" different RGB numbers for hundreds and hundreds of colors, lol
