KDE4 introduces some major changes in color schemes. Here you will find an overview of some new color-related features, as well as a preview of the new color schemes.
This should probably go somewhere better (like, "the documentation"?). For now techbase (with winterz' "highly-unofficial" permission) is being abused as a dumping ground for screenshots, in order to try to solicit feedback from kde-artists.
The "Common Colors" set allows setting the most important colors in one place. Note that "Selection Inactive Text" means "Inactive Text" belonging to the "Selection" set, and is not related to inactive effects in any way. Also note that currently no auto-calculation is performed, so you need to go to each set to specify the alternate background color.
KDE4 introduces "state effects"; three effects that can be applied to inactive windows, and disabled widgets.
NOTE: Inactive effects cause additional window repaints that some people may find annoying, or may cause performance problems on older machines.
The author (Matthew Woehlke, also the creator of all of these color schemes, with varying levels of inspiration or blatant copying) apologizes for the marketing spiel you are about to be subjected to if you read this section ;-).
Rich blues, vibrant yet soothing, threaten to pull you into the watery depths of this scheme. This is a port of the KDE3 scheme by the same name.
Bright, shiny gray with just a touch of blue, combined with vibrant blue accents, conjures the feel of polished metal, as well as memories of Keramik and Plastik schemes from KDE3.
Soft shades of sand are accented by rich red. This scheme is a port of the KDE3 scheme by the same name.
Rich orange reflects moonlit dunes, while striking blue reflects the sky above, in this echo of a desert at night. (Brought to you by the same dubious idea that produced Water Orchid. Also likely to go.)
Dusty gray-purple with touches of green bring to mind a lilac bush on a warm summer night.
Pale shades of green with a touch of blue accents evoke images of grass-covered hills shrouded in fog.
Soft shades of gray touched by yellow mix with honey-colored highlights to give an impression of bees, or perhaps BeOS.
Dark shades of green shimmer with unearthly light in this scheme inspired by the glow of a sea of lush green grass in the deep of night.
Kudos if you can figure out the reference here. Due to questionable content, it will not be posted ;-). This scheme added at the request of Eike Hein, and inspired by Charamel for Firefox
Inspired by movies of dark waves breaking against tall, black cliffs, this scheme (a dark version of Whitewater) is perfect for those that love a sense of foreboding, or just the rich, natural look of volcanic glass.
Soft shades of red invoke feelings of muted passion.
Warm gray, subtle gold, and striking cyan come together in a warm industrial tribute to classic skyscrapers in the late afternoon sun.
Rich gray with a hint of floral meets soft cyan and vibrant royal-purple accents in this scheme inspired by orchids, and KDE3's Solaris.
Gray mingled with green joins blue accents in this outdoor scheme inspired by grass and rocks against a clear sky.
Attempting to bring to mind a beautiful purple flower against a turquoise background, this scheme instead looks like a mad candy store. (Here we see the peril of making color schemes from wallpapers, and a Microsoft one at that. This one is almost certain to get the axe before 4.0.)
Inspired by a juice label, this scheme brings pale-but-bright peachy reminiscent of juice by the same name and welds it with floral green accents.
Calling to mind the river canyons of Colorado, this neutral scheme features a deep, earthy/rocky gray base with blue accents.
Created from the KDE3-era wallpaper of the same name, this scheme was made by Matthew Woehlke, who uses (and has used, for about two years) it as his KDE3 scheme.
Reminiscent of the computers in the fictional city of the same name from the Matrix trilogy, this scheme features mainly black foreground elements on a starkly white background. It is included in kdeaccessibility and is intended to aid users with visual difficulties.
An inverse of the Zion scheme, this provides white-on-black elements, again maximizing contrast.
