Questions about coloring online

How the free pages, credit pages and your own photos work — and where your progress is kept.

All questions
Is online color by number free on Mosaci?
Yes. Every page in the Free tab can be colored in your browser with no account and no credits. Extra pages in the "Unlock with credits" tab cost 1 credit each, once.
How do I color by number online?
Open a page, pick a color from the palette, then tap or drag over the cells marked with that color's number. Zoom in for small cells; the page is done when every cell is filled.
Is my coloring progress saved?
Yes. On free pages your progress is saved in this browser as you color. Pages you unlock with a credit are tied to your account, so you can continue them on any device.
Does it work on a phone or tablet?
Yes. Coloring runs in the browser on phones, tablets and desktops — there is nothing to download or install.
Can I color my own photo?
Yes. Sign in and use "Color your own photo" to turn a picture into a color-by-number page. Coloring it uses 1 credit, once — the same credit as downloading it. These pages are kept in your browser; use Export / Import to continue on another device.
