Re: [Gimp-user] Re-hue-ing a graphic

Yes and no - it's exactly that sort of user-interface I am looking for, but to be able to set the hue of an existing graphic. If I go into Layer-Colours-Hue/Saturation, then click 'Master', moving the 'Hue' slider bar alters the hue of the whole graphic (which is one single colour on a white background). I want to do this effect, with a colour chooser interface. Is that possible?

[Gimp-user] Re-hue-ing a graphic
Hi All, Can anyone help me to do this? I look after a small on-line magazine and they have a mast-head logo at the top of several pages. This is in colour, but only different saturations of the same colour. Each month, the print-designer changes the colour of the text headlines and the mast-head to match. I can always see the HTML colour selected (color=#XX) for the text and need to track the masthead colour to match. How do I get the Gimp to exactly track that hex colour - is there somewhere I can input it as a value and just it promulgated through the graphic at the existing saturation and lightness?

[Gimp-user] Newbie Question
Hi All, I have a first-time question. In general terms, how can I change all the pixels of one colour within a hand-drawn selection into another colour ? In specific terms, I have a gif file containing some black-on-white text. I want to be able to colour various parts of the black text to be red-on- white, or blue-on-white (whatever) for emphasis. I can't do that colouring on the originating system, so need to uyse the GIMP to do it. I tried the colour-to-alpha idea suggested in the first background-colour change tutorial, but colour-to-alpha is greyed out and I don't how know to get past that, if it is the right way to go. Any suggestions ? Jonathan ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
