Back in 2008, PJ member 7even suggested a legendary challenge idea:

To pixel a medival knight, using one of these 7 prompts and the 7 colors that belong to it.

7evens obsession with knights led him to create the succesful game Rogue Legacy, but with 90 entries to the weekly it was clear that more pixel artists are fascinated by these characters!

Which is why we're rerunning the challenge! So to recap:

Pick a number from 1 to 7, and create a 100x100 image of a knight using the 7 colors of the palette (no black & white, no mixing from other palettes). As always, mutliple entries are allowed.

Canvas Size - 100x100 exactly.
Colors - 7 colors, from one of the 7 palettes.
Animation - No.
Transparency - No.

Do you have a perfect idea for a weekly challenge? Something that is well defined/restricted, but still open to creativity? We would love to use it!

We've made this forum thread where you can submit your idea, or comment with suggested improvements on others. There is no guarantee on if/when/how we might use it, to keep the upcoming challenges exciting and fair for everyone. But if "your" challenge takes place, you are of course welcome to take part too!

This year we met a visitor who comes to us every 6766 years. We will hardly be able to enjoy its short-lived brilliance again. In its honor, capture the scene of the celestial passer however you want; the condition is that the comet is the dominant part of the scene.
 

The palette for this challenge is SLSO8:

Canvas Size - 120x100 max, either horizontal or vertical.
Colors - max. 8 colors, only use colors from the SLSO8 palette
Animation - Optional.
Transparency - No.

We have opened an official discord server!

Discord is a chatting service, and we have opened the server to talk about pixel art, get quick feedback, or just general chat about games, hobbies, or anything else you wish to share with fellow PJ members! Right now we are a group of 20 people, and we wish to keep it relatively small, cozy and friendly.

The server is for PixelJoint members only.
