Unused colours

So’s I need a good image editor for at least one function that doesn’t seem to be in PSP, at least not the version I have. I have these:

made by Shiny? I think?

Anyway, they need to replace the kinda ugly grey castle tiles, only they have some colours not on the regular pics 1 palette. I determined that pics1.png, at least the butchered version that I’m using for G:tA has at least ten unused colours on the palette, but I have no way of determining which ten those are. I’ve only known of one program with the function to separate the palette into used and unused colours, and it was iDraw, but iDraw tends to not like graphics in general. It’s good for low-quality pixel art where you can trust the transparency to work itself out (does perfect for RPGMaker 2003 and such) but I wouldn’t trust it with my pics1.

Anyone know a program that can at least point out the indices of colours that haven’t been used in a picture yet?

If you’re talking about the restricted pallette…

Picture:

You can see how the pallette changes from 16million colours to just 256 and how it trys to keep the image colour quality (though that picture it has alot of colours its trying to use haha)

I use PaintShopPro7 and it has the ability to automatically set the pallette, choose the colours that match closest and then limit it to 256 Graal standard and also setting custom transparency. All with pretty much 3 clicks, if this is what you’re talking about then you can technically use whatever colour you want, if it isn’t what you were talking about then sorry I didn’t understand you D: lol

Well, no, that doesn’t really help, but thanks for trying. I know how to limit the palette of the image itself, I just need to figure out the ten or twelve colours that pics1 isn’t using so I can change/use them.

have you tried paint.net?
maybe it’ll help.

Typically if you save an image, it will purge out any colors from the palette that aren’t being used. If they are staying in the palette, then that means they’re being used SOMEWHERE. Typically when I want to clean up pics1 color-count, I:

  1. Get rid of volcano tiles. A lot of colors wasted for tiles never used.
  2. Clean up tiles that use a lot of colors. The new trees, for example, use a crapload of shades of green on the leaves. It’s a waste, and can be simplified down to just a few shades. The swamp statue also uses a HUGE amount of colors since it was shaded with gradients.
  3. Get rid of any other tiles you never intend to use. More importantly, do this with the ‘newer’ tilesets that Koni added back in 2001. He didn’t do a very good job of making them clean, color-wise.

Yeah, my version of PSP only understands 2 colour, 16 colour, and 256 colour palettes, so unfortunately I can only seek out the unused ones. I’ll try Paint.Net though. I was planning on using that along with the Gimp after I phoenixed my computer and hoping that together they’d have everything I needed.

Most paint programs will tell you the number of unique colors in an image. I don’t know of any that will tell you which palette indexes are unused. What you CAN do is set a palette index to black. Then see how many unique colors there are. If the number of unique colors stays at 252, then you found an unused index. Joy.
