Of course, it's all for your own color preferences.īelow is the screenshot of MildDark theme for TKE editor. The new features of tk_chooseColor ( Move all, Tone moves) would be helpful for shifting the foreground colors. At the night light you would have a less contrasted version of your theme. At the day light you would have a more contrasted version of your theme.Ģ.
For this, all you need is to shift all your colors to one or another side of tk_chooseColor:ġ. at the cloudy morning, bright day or coal night. Well, if you've developed a nice theme, you probably would wish to use it at the different lightings, e.g. the comments' color.Īnother consideration is applied to a set of themes. The only exception is relevant for those colors that should be about the background's side, e.g. This equality means that we would get a balanced set of colors in the resulting theme. The main thing is their average that also need not to be awfully exact - it's enough to have a rough equality. They need not even to be of 'equal form' (B at left, G at middle, R at right). For example, this way:Īgain, the color averages need not to be composed as coinciding with a selector. Having a dark background, we should select our foregrounds at the right (light) side.Īt that we should select them so ( which is most important!) that their averages to be more or less equal. We can tone the background with a warmer or cooler color, as seen on the picture below: We are selecting for TKE editor the dark background and the light foregrounds. Here it happens to coincide with B selector, but it's not a must.Īlso we should remember that the left side of color bars is shadowed dark, while the right side is shadowed light. Here we would develop the color theme for TKE editor written in pure Tcl/Tk btw.įor this, we should mark the following parts of tk_chooseColor (a current localized version of it): Applying Tk color picker to a color design The example of theming is considered below. The tk_chooseColor is very helpful in the designing of color schemes, e.g. You can simply enter brown in the entry field and tone the hue as well. At that, it's enough to know that brown contains no blue. They are located at both sides of tk_chooseColor's selectors.įor example, in tk_chooseColor you can easily locate the brownish range of colors (terra incognita for some color pickers). and their tones.īut what makes tk_chooseColor so remarkable is that you can easily see and access all neighboring colors for the selected one. All those red, green, blue, cyan, magenta, yellow, olive, purple, teal etc. Using only three 'magic' numbers (0, 128, 255) you can get a combination of 27 colors which are nearly all you need - primary, secondary and tertiary ones. These sortings are useful when you need to view some analogous colors that are close to each other by not their names but hues.ģ. You can see all Tk standard colors sorted by Red, Green and Blue values. You can see all Tk standard colors sorted by names. This feature is also demonstrated on the video. You can input a Tk standard color name in the entry field. In tk_chooseColor you can move (and would find it very convenient) any selector with clicking and dragging the mouse over the color bars. Useful features of tk_chooseColorīefore exploring a usage example of tk_chooseColor, let's consider few features of tk_chooseColor that are not too obvious.ġ. A stand-alone Tk color chooser is available (1st screenshot above). For comparison, two themed choosers are shown beside on the screenshot.Ĩ. The -moveall (0 by defauls) and -tonemoves (1 by default) options are added.ħ. The RGBCMY and their tones are added, in separate color boxes.Ħ. The 'Tone moves' checkbox is added allowing to implement the toning feature for a current color.ĥ. The 'Move all' checkbox is added allowing to move all (R, G, B) selectors simultaneously.Ĥ. The default sizes of Tk color picker are changed a little for more usability.ģ. The resizing of window is locked (supposedly the resizing makes no sense, at least in the current version of tk_chooseColor).Ģ. The changes to tk_chooseColor are the following:ġ. Nevertheless, I would try and show some remarkable features of tk_chooseColor which are enhanced with my little changes, available here:
Of course the coolest of all is Mac OS' color picker implementing the color circle. Though, the Windows' color picker is somewhat cumbersome, except for its toning bar which is very good feature. Probably tk_chooseColor looks like an ugly duckling among its tough 'Big Brothers'. The native Tk color picker (tk_chooseColor) is used in Unix platforms as they have no default color picker, while Windows and Mac OS have.
