#### A color selection dialog written in GTK+ 3 by Jente Hidskens

Ever wanted to know the value of that color on your screen? Gcolor3 enables you to pick the color from any pixel on your screen. It also offers a palette, so that you can easily mix and match a couple of colors together.

When you have found the perfect combination of colors, naturally you want to save them. Gcolor3 allows you to conveniently save and retrieve colors.

Gcolor3 is a color selection dialog written in GTK+ 3. It is much alike Gcolor2, but uses the newer GTK+ version and other modernisations to better integrate into your modern desktop.

## Enable snaps on CentOS and install gcolor3

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.

Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions.

### Enable snapd

Snap is available for [CentOS 7.6+](https://snapcraft.io/install/gcolor3/centos), and Red Hat Enterprise Linux 7.6+, from the [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The EPEL repository can be added to your system with the following command:

```
sudo yum install epel-release
```

Snap can now be installed as follows:

```
sudo yum install snapd
```

Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled:

```
sudo systemctl enable --now snapd.socket
```

To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`:

```
sudo ln -s /var/lib/snapd/snap /snap
```

Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.

### Install gcolor3

To install gcolor3, simply use the following command:
