Replacing color in PS

[TTHacken]

I am trying to replce a colour using adjustments->replace color and it doesn't work! it selects the colour to be replaced fine... then I choose the colour I want it to replace... then? nothing, the colour remains the same!! I can't tell you how frustrating this is? There seems to be nothing I can do, it just refuses to change the colour even with fuzziness on 200! I have tried everything, it is as though it simply doesn't work!!!!!!!!!!!!!!!!!!!!!!1

what am I not doing? :mad:

Only using PS7 but...are you trying to *eyedropper* your new colour??? or are you using the the HSL transform sliders? the former will not work (doing this just changes the *to be replaced* colour), the latter should.

[TTHacken]

I think I am using the sliders - I get a window with two colour patches - the top one says it is the colour to be replaced - and when I click on the bottom patch i get to pick a new colour and that automatically adjusts the sliders. But nothing happens...

This is what you should be seeing TT maybe slightly different if you're on a PC. Use the colour dropper on the colour in your document you wish to change which will then show up in the "color" window. You can then adjust the sliders to alter all occurences of that colour in the document (or selected area)

Hope this helps!

Teej - that is exactly what I see, I get the eye dropper, the colour I want to replace appears fine, I then choose the colour I want and nothing...

Does the 'layer mask' have anything to do with this?

[Broacher]

You're probably trying to select a colour while focused on the layer mask. Make sure the image, not the layer mask is selected.

[Ghastly]

Layer mask???...you never said anything about a layer mask in your first post ;) ...well I tried to recreate your problem but by acting only on a mask I had only access to the lightness slider, which of course is logical! (only parameter that affects alpha here)...might sound a bit daft this but if you had a layer mask then the hidden areas might be the easiest thing to select and thus any operations you try to perform on the image will not be permitted due to the fact that it is not in the selection...gonna mull this over a bit more though.


Hmm working on the principle that *that is exactly what you see*...perhaps the selection you are working with is corect but the layer it acts on isn't (it might be a nasty empty one...such that you see white like in the picture shown)...this would also prevent replace colour from working

You can do it with the magic wand. Just make sure the contiguous checkbox is not checked in the options at the top and click the color you want to replace. Then use the paint bucket to fill it in with the new color.

OK - here is my screen, the layer mask has nothing to do with it at all - I thought I might need one because there wasn't one! I have noticed that when I first do the colour selection it comes in as grey when in fact it should be black... but here is the screenshot - you can see that preview is on and nothing at all is happening: and it is not 'text', it is an image, transparent background. When I use 'selection' instead of image I get reversed colours showing up!

K...I've had a play with this command and colours/colour modes in general...tried to find certain rules but always I get tripped up at some point with some strange little quirk..what seems pretty clear is that though blacks/greys have no hue and also have no saturation of *no hue*...it seems you cannot just add hue and since you cannot change the H component you cannot change the S component of HSB either. you can however change the B component though (the extent to which you can change it depends on whether you're in CMYK or RGB...the latter having a greater effect)...you can piss about with colour modes and get some success by trying to force a change of values but as suggested there are easier ways to swap your colours :cool:

If I connect any more dots I'll post my findings later. (though the more I try to explain what's happening the more I feel like a child trying to explain physics on account of noticing which way his toys fall...I have never taken the time to learn in depth how P.shop handles colour...sorry)

[TTHacken]

Hey Ghastly, believe me I am feeling the frustration! I don't know one tenth of what you do but I know that this colour replace option ain't all its cracked up to be - should be called 'maybe under some circumstance replace colour'. I too wish I could work out what the conditions for colour replace are that I am failing to meet!!

If anyone wants my file to see if they can work out the problem let me know and I'll email it - it is just under 8MB.

TTHacken, I'm curious, is your problem that when you converted them to CMYK your black text etc. come out slightly gray with elements of all four colors?

[TTHacken]

Kool: there is a grey boarder around each letter and the colour is strange - certainly not 100%K which is what I was expecting - but the real problem is that the background image was changed by the artists from CYMK to 1bit which meant that the text colour had to be altered and hence the desire for a colour replace. The file is just refusing and that's that - switched the whole project to Indy out of frustration!

[cornfed]

Just out of curiosity, why are you laying all of that text out in ps?

[TTHacken]

cornfed: 'cause it made sense at the time!
