Also, RGB is an additive color model and only works for devices emitting light. If at all, you can convert Pantone to CMYK, but that won't help you much, since your monitor stays at RGB and the sRGB colorspace is very limited anyway.
    fair enough, but its still confusing.

    That makes sense I suppose, still confusing that they use different codes and the colours look different.

    I've been watching a lot of power tool and tonka truck restoration videos recently, and I think most PCs are powder coated. I've seen a few videos where power tools were powder coated to a similar or the same sort of texture as vintage PCs and compatibles have. I think it's a part of the chemical makeup of the paint that causes it to dry that way.

    The IBM color per that forum posted as Pantone 413 U. I thing my songcheer XT case on my 486 is a similar color.

The final cure is 7 - 14 days, so I will update once I have some results in a few weeks.

    Please do update us. I am interested to hear if you can get the same feel and hardness as the original paint...

    Just got a matt rattle can of cellulose 413U paint.

    Its colour is a reasonable match, it has that 'greenish' colour but its looking lighter than the original, but that might be because the original paint is so dirty.

    No pictures until I have completed, but the case will need a full rub down due to the damage and will have to lose the speckled effect or it will look daft. Haven't managed to find a way to replicate it, but as its matt, an initial test spray actually looks fine.

    All done

    Not been able to recreate the finish and the pictures don't do justice to the colour as the LED lighting is too white, but I am happy

    Not too bad to say it was badly smashed.

    Nice job! You may want to take some picture in natural light to better illustrate the color if the LED lights are not working for you.

    How does it feel to the touch?

    Its smoother. It was either that, or a great big smooth patch on the side which stood out like a sore thumb. The full matt paint goes a long way to making it look ok.

    Sorry, I wasn't very clear. I am not talking about the orange peel. I am talking about the general feel of the paint. The original paint is "slick" for the lack of a better word. Hand slides over it. I feel like the latex paints, even when I spray with a gun, tend to be "rough". I am wondering if the paint in the can or mixing it with the hardener made any difference.

    Hum, get what you mean. Despite the bumps, the original is almost 'slippy'. This feels more 'matt'. I have used cellulose paint and you cant get it mixed with different Matt levels, so that might help. I have also found some Stone Effect spray paint that looks as if it will produce the same texture, but to be honest it looks fine as it is.
