Overview

Eyedropper

A powerful color picker and formatter.

Features

Pick a Color
Enter a color in Hex-Format
Parse RGBA/ARGB Hex-Colors
View colors in Hex, RGB, HSV, HSL, CMYK, XYZ and CIE-Lab format
Customize which formats appear as well as their order
Generate a palette of different shades

Future Features & Roadmap

Generate a palette of similar colors
Add more color formats

When should I use this? And when not?

This application is geared towards advanced users (developers, designers, etc…), who not only need to pick a color but also modify or view it in different formats. For simply picking a color on Gnome, the color-picker extension is far better suited.

Translation

Translations are a great way to contribute. This project uses the GNU gettext for translations. If you want to learn more, visit the translator section.

The easiest way to add a translation, is by importing the Eyedropper.pot file into a program like Poedit or Gtranslator.

After finishing the translations, add the translated language code into the LINGUAS file. Then follow the above steps to create a pull request. Please also state in the description if you are willing to maintain the translation.

Building

See this general guide for building the project using GNOME Builder.

Alternatively use this VS Code Extension for working inside VS Code.

Building manually

Alternatively, it is possible to build the project manually using flatpak-builder. First install the required sdks:

flatpak install org.gnome.Sdk//43 org.freedesktop.Sdk.Extension.rust-stable//22.08 org.gnome.Platform//43

Then build it using:

flatpak-builder --user flatpak_app build-aux/com.github.finefindus.eyedropper.Devel.json

To run it:

flatpak-builder --run flatpak_app build-aux/com.github.finefindus.eyedropper.Devel.json eyedropper

Build without flatpak

meson --prefix=/usr build
ninja -C build
sudo ninja -C build install

Updated French translation

I updated the fr.po file

PS : running Eyedropper in GNOME Builder to check the new translations to add, I noticed that icons were missing in the preferences panel (see screenshot below).. Is this bug due to GNOME Builder ?

"Failed to pick a color"
When clicking on the eyedropper or pressing ctrl + p: "Failed to pick a color" appears at the bottom of the window.

In the terminal: ERROR eyedropper::window > Portal request didn't succeed: Other

This happens with flatpak and if built with gnome builder.

Only happens on window managers. Works fine on gnome.

Color picker opening is too abrupt
Describe the bug When going through various windows of the app, it's smooth most of the time, in the sense that opening windows animate, they don't just appear out of nowhere. This is not the case with the color picker window (the one that appears after clicking "+"). You can see that in the Screenshots section (although it is a WEBM).

To Reproduce See the WEBM

Expected behavior I'd expect the window picker opening to be animated just like all the other windows.

Screenshots

You can see the difference between the first window popping up and the second one. The first one is animated, the second one is not.

Missing icons in GNOME Builder

Compiling the latest code in GNOME Builder (on Fedora 37 / GNOME 43) I noticed that some icons were missing in the Preferences Window (see screenshot below). (Previously all the icons of the 'General' tab were missing, but it seems to be ok now)

Add labels to history buttons

If you are taking a many colours that are similar but different, it might be hard to (re)find the correct colour within the history.

Adding labels (#hex representation) would help "power" users to refind a colour from history with fewer clicks.

Because this feature would only help power users and increase the size of the history (in the GUI) quite a lot, it would be best to make this optional. Or enable it automatically, if the app detects that colours are too close to each other.

Don't launch with an arbitrary `#2E3440` color, always show the current color in the sidebar to the right when there's more than two colors, and let me delete colors

I'm running the flatpak version from Flathub, on Fedora. By default, the app launches like this, with color #2E3440:

This is a problem when I want to sample colors that actually are close to this, such as #002E41. I then basically can't tell stuff apart from your default color, and I can't clear/remove the default color. Additionally, when you click a color on the right it "swaps places" with the color details on the left, which then goes into the right, and it means the colors keep shifting around all the time, so if you have a couple of similar-looking colors it's absolutely impossible to keep track of because the list keeps being reordered.

Please have the app start with a blank slate with just a "Pick a color" button, then don't swap things around when I click them in the sidebar (they should rather act like tabs, functionally speaking) and if I made a mistake and picked the wrong color, let me right-click and delete it (or have a delete button in the color's details).

[Feature Request] Use AdwAboutWindow

Is your feature request related to a problem? Please describe. Nope.

Describe the solution you'd like Since this application uses libadwaita, imo it can use adwaboutwindow for more consistency.

Describe alternatives you've considered Of course, not change it.

Additional context Nope.

Information Isn't related.

Created French translation
I created fr.po + updated the LINGUAS file

I also noticed some typos in the source strings :

"cmky" instead of "cmyk"

"alpahvalue" instead of "alphavalue"

(I corrected them in the fr.po file so they won't appear in the french version)

I also noticed that the strings in the toast notification "failed to pick a color" doesn't appear in the .pot file

Removed duplicates from history

Imagine you select a sequence of colours. And by accident or without knowledge you pick a colour twice or thrice, which easily happens when colours are very similar.

To illustrate the problem with duplicates in the history:

The green and red in the history are listed twice, but are the exact same values.

I think that only keeping the most recent occurrence of the colour in the history would be a good idea. But I am not 100% sure. Some people might use the order of the history to remember the context where they took the colour.

Maybe some other users of the software could chime in.

Feature: Launch hidden with global shortcut

I'm a designer and developer and as far as I know, there is really no eyedropper on the market that does this:

Launch hidden on startup > Ability to pick a color with a shortcut (only picker, no app GUI) > automatically copy to clipboard (with the pre-defined format I would set).

Think of it... This is the fastest, cleanest, and smoothest workflow anyone user can imagine. Actually, I didn't bother to tell developers this before but when I saw this tool, I thought it was almost the complete one I've ever seen. And hope you agree and make it possible.

Big thanks for your great work!

Distribute as AppImage
Is your feature request related to a problem? Please describe.

Currently I am using the AUR package and upgrading takes forever due to the compilation step. It also requires rust and ninja to be installed locally, which I otherwise not need and they take up a lot of space.

Describe the solution you'd like It would be great if eyedropper would be offered as AppImage install, since that is much more consumer friendly.

Describe alternatives you've considered Stick to AUR
