People keep asking why not just use the 'color' filter, and here's why. Color destroys pictures, ESPECIALLY if you have any sort of shading, it will degrade your lineart. Here is a side by side comparison of using a color filter vs using a hue filter as outlines in my tut: [link] Note you can no longer even see his eyelashes using 'color', his hair looks like crap and and the dark shading is completely shot. Using 'color' will NOT give you the same result as using 'hue'. Here is the picture used btw: [link]
People keep asking me how I do it, so here's exactly how! It's a huge image so give it a few moments to DL. If you can't view it on a full view just hit 'download' there to the left and it'll bring it to full view. It's a little condenced due to size restrictions, but I hope it still helps :3
Picture used was a doodle I drew for ~nolavon the other night while we kept each other up to ungodly hours XD. Character is hers, art is mine.
Enjoy!
Feedback apreciated as always so that I may improve my tutorals, let me know what you like, what works, what doesn't.
Can you give me a screenshot of your workspace including your layers menu with the colour layer selected and the whole workspace (bar above the file menu included) visible?
Your lineart needs to be a colour, not solid black. Colour based layers like colour and hue can not effect solid black or solid whites. You may find my other tutorial helpful if you are working with a solid black line to give it a colour: [link]
Brown will work, gray will not work with a hue filter because gray has no hue to manipulate. You can set a colour filter over a gray layer but it does not look as nice as simply making your layer a colour (like brown) and setting a huge filter over it. The colour itself doesn't matter, but the saturation of the colour will effect the intensity of the rainbow over it.
thank yoU!
