I am looking to change the colour pallette of an existing template (in my case Optimus from Joomlashack).

EZ Palette Editor looked like exactly what I was after
But then I realised EZPE only changes CSS colours which is fairly ineffective since many of the colours are in set in PNGs.

Is there a component that shifts all the template colours from say a green pallete to a blue palette?

Or should we get together and produce one?

Hello - do you mean you want visitors to be able to change the colours of the website - or you just want to change them from the backend.

demo.rockettheme.com/apr08/index.php is a rockettheme template that does this from the front end

The only options I can see with pngs - is having multiple pngs in various colours - and having a variety of style sheets.

Unless you just wanted to use a filter - kind of like a colour filter over a camera lens - and if you started with colourless pngs (like grey gradations) - you could apply filters (opaque but coloured layers) over them...

Generally when altering a template with pngs (or any background images) - I find the the pngs need to actually be manually created. I don't know any way around this - unless you just take them out and code in borders and background colours instead (but obviously then you lose image effects like gradients and drop shadows).

Thanks for the response JLJ. I'm responding here so we don't end up with a long chain like some of the other threads.

So, a bit of clarification: I really originally saw this as a one off process to shift a preexisting template so it as closely as possible matches the client's colour preferences &/or logo.

I've got an instance where the client's preference colours are just subtly different from the the colours in a standard Optimus template.

The problem is indeed in PNGs where there's colour gradation where one colour bleeds into another.

I'm thinking it must be mathematically possible to shift each colour to an appropriate new colour. Maybe your filter suggestion is the solution.

Other people have suggested that it may be possible to leave the template exactly as it is and then shift the pallette on the run - that's probably rather too complicated for me.

Don't know if I've missed something here, Mate.

It's quite easy to change the colours of images in a graphics programme. I use the GIMP (because it's free) but you could do it in Photoshop or other image programmes.

You can create or alter gradients, change the hue or colour fill images.

The hard part is being sure you've got all the right files and getting the right colours in the right places.
