| − | =Colour features issues= | + | ==FG Invert Color== |
| − | Different requests and issues around Colour functions/features.
| + | ===Concept=== |
| − | | + | In the painting tasks, are very important to work with different methods to select or to choose colors. |
| − | ==Colour Swaping==
| + | The complementary colors is commonly utilized by all artists. |
| − | ===Main Scope=== | + | ===Improvements reasons=== |
| − | Swap a "fixed number" of colours used in each session, via a toggle shortcut key.
| + | To invert a colour is necessary many steps between pick and wheel colors dialogs. With a shortcut these actions are more immediate and, the painting session has less actions and steps with different color dialogs. |
| − | | + | ===Invert color of FG=== |
| − | ===Current possibilities===
| + | Add a toggle shortcut to invert the current colour on FG. |
| − | * Swap between FG/BG Colour via keyboard shortcut → screenshot Configure Keyboard Shortcuts.

| − | * Scrolling between the swatches of the current palette via Keyboard Shortucuts.
| |
| − | The 'context-foreground-palette-...' and 'context-background-palette-...' to scroll the all swatches of a palette. Is very interesting this possibility (thanks to Massimo Valentini), but apparently this is broken... in my DE, GNOME 3.10. See the bug report → [https://bugzilla.gnome.org/show_bug.cgi?id=765817 Context actions do not working.]<br>

| − | <div style="width:50em; padding-left:1em">''I experimented a bit with these actions and I have found that they only work if the 'Palette Editor' is docked or at least open. So one has to open Windows->Dockable Dialogs->Palettes and double click on a palette, this way the 'Palette Editor' is opened and after that these shortcuts start working. They keep working even if the dockable is not the active tab.''</div>

| − | (*) The swatches (two rows) could be understood as a palette built, on-the-fly, during the work sessions by the user in three ways:<br>
| |

| |
| − | 2) via drag and drop colour in each swatch or;<br>
| |
| − | 3) via picker colour, but is added only after the colour is used on canvas. Each new colour is placed, always, in the first slot (left-side of first row), and the displacement of colours happening versus right-side direction to each new colour that is added.<br>

| − | ===Improvement Reasons=== | |
| − | Enhancing the General Usability → [1] to have a fast way to access the history colours used in each work sessions; [2] to avoid excessive use of steps, ''via mouse mainly'', between paint tools tasks (repetitive stress), see [http://gui.gimp.org/index.php/Topics_to_Digital_Painting_with_GIMP#Scenario_.7C_Float_full_or_dockable_.7C_Single_Window test below]; [3] Swapping color without necessity to use the traditional dialogs... the session task is more focused and simple.

| − | To choose colours is necessary minimal 2 steps and maximum 3 steps (cursor movements and clicks).
| |

| − | The sample has 6*6=36 rectangles, only to select colours for all rectangles, we must crossing or move the cursor and do clicks at amount of a minimal 72 and a maximum of 108 times.

| − | * History colour pop-up, for instance, with the last 6 colours stored in history of the FG/BG Colours dialogue. This pop-up is enabled when hit the key shortcut action.
| |
| − | * Each time that raise finger from key and hit again, the selection colour goes to next colour, for instance, from A to B, and successively until F and in a closed cycle. The principle is the same of the short-cut to swap colours between FG/BG, but in this case we have 6 colours.
| |
| − | * Each time that the key short-cut is held down, the colour remains stopped in the slot, for example A.
| |
| − | * The cycle is stopped naturally after a lapse time between hit key and raise finger of key.
| |
| − | * Have on GIMP preferences the possibility to choose the amount of colours to use in this pop-up, for example, minimal 6 and maximum 12 colours.

| |
| − | | |
| − | ===Improvement Reasons===
| |
| − | To graphic design, painting, certain swatches must be of a kind fixed as swatches on canvas (ready as colour tube or reference colour of a layout page). Each work has a fixed number of these swatches... and other are random or temporary. For an artist or a designer, e.g., the fixed swatches are placed on the bottom row. The mixed swatches, the variations (all pick colours) of the first row swatches are placed in the first row.

| |
| − | <div style="width:50em; margin-left:1em;">''Well, the first thing I do when I want to paint is pick some colors to paint with.''
| |
| − | | |
| − | ''The way things are now, every time I pick and then paint with a new color, the swatches and also the palette tab colors update and rearrange themselves, so I have to keep looking for where the color I want next has moved to. And sometimes the colors are not easy to tell apart just by looking at the swatches, partly because the swatches are small (and need to be small) and partly because GIMP color picker/foreground tool isn't color-managed (and really needs to be).''
| |
| − | | |
| − | ''So that's why I make a layer and paint color swatches for the colors I want to use. But this also is awkward. Having a fixed palette of swatches on the pick foreground tab would be very, very convenient.''
| |
| − | | |
| − | ''Having the top row of swatches update the bottom row be fixed (even after closing GIMP) unless/until deliberately changed would seem to be ideal, but of course would need testing to be sure.''</div>
| |
| − | | |
| − | ===Improvements Schema===
| |
| − | Is very useful to divide the two rows with different scopes (Elle Stone Suggestion):
| |
| − | * Top row is set once and remains until is not deliberately modified/reset;
| |
| − | * Bottom row changes as new colours are picked.

| − | ==Colour Internal Tabs of Colour Dialogs==
| |
| − | Implement the possibility to have as independent tab, the internal tabs of the picker colours GIMP, Wheel and Palette.
| |
| − | ===Current Colour Dialogs===
| |
| − | The different pickers are as tab on the Change Foreground Color Dialog or as button to select each picker as is on the FG/BG Colour Dialog.<br>

| |
| − | | |
| − | ===Implementation Reasons===
| |
| − | The more complete dialog is the Change Foreground Colour Dialog, but is very invasive on canvas. To have the main picker colours as independent tab is possible to think in the docks where we have two or three views of colour instances. For instance, GIMP picker + Scales or Wheel + Scales.

| − | ===Implementation Schema===
| |
| − | Transform the internal tabs of GIMP, Wheel, Palette and Scales in the independent tabs.

In the painting tasks, are very important to work with different methods to select or to choose colors.
The complementary colors is commonly utilized by all artists.
To invert a colour is necessary many steps between pick and wheel colors dialogs. With a shortcut these actions are more immediate and, the painting session has less actions and steps with different color dialogs.
