Fluid Art:Color By Number

Review by eFreeware

If you like the idea of paint-by-number apps but find the usual landscapes and pet portraits a bit tired, Fluid Art: Color By Number is built around a different look. Instead of filling in a cartoon or a photo, you work on fluid-style images where the colors blend and swirl as you go. The developer describes the result as a liquid effect that mimics real fluid art, and that is the whole pitch: guided coloring with a more abstract, flowing result.

The game is free to download, carries ads and offers in-app purchases. It has been installed more than 500,000 times and holds a 4.8 average from 10,394 ratings, which is a strong signal for a coloring title. It was released in August 2023 and was last updated in July 2026, so it is not a forgotten project.

This is a game for people who want to switch off rather than compete. You follow numbers, fill areas with color and watch the picture come together. If that sounds like your idea of a wind-down activity, the rest of this review covers what the app actually asks of you and where the limits are.

What makes the coloring different here

Most paint-by-number games treat color as flat blocks. Fluid Art: Color By Number treats it as something that moves. Filling in the liquid colors makes them blend and swirl, so the results look like real fluid art. That is the feature the whole app is organized around, and it is the reason to pick this over a generic coloring book.

The subject matter follows from that. The library is made up of fluid-style images rather than the usual mix of animals, flowers and city scenes. The pictures are grouped into themed categories so you can pick a mood rather than scroll through one endless list, and the New category is refreshed daily with fresh pictures. For anyone who colors regularly, that daily churn matters more than it sounds: it means the catalog does not run dry.

I would expect the appeal here to be strongest for people who enjoy abstract art and marbled patterns. The swirling effect is the point, so if you want a coloring app that produces a recognizable subject at the end, this one is built around something else.

How the coloring itself works

The core loop is conventional paint-by-number. You choose an image, open the coloring page and follow the numbered prompts and the palette the game provides. Each number corresponds to a color, and you fill the matching areas until the picture is complete. The developer calls this a guided approach, and that is accurate: there is no drawing skill involved and no decisions to make beyond which picture to start.

What the app adds to that formula is the liquid behavior. As you fill areas, the colors blend and flow rather than sitting as separate shapes, which is what gives the finished piece its fluid look. It is a visual reward layered on top of a familiar mechanic, and it means the process is more interesting to watch than plain block filling.

The app is presented as a relaxing, meditative way to unwind from daily pressure. That framing fits the design: the interaction is simple, the pace is yours, and nothing in the core coloring loop is timed or competitive.

Daily images and the stamp system

Alongside the main catalog there is a Daily Fluid Feature. Each day the app highlights one premium fluid image to color, and completing it earns you a liquid stamp. Stamps build up toward honors, rewards and more pictures.

This is a light progression system rather than a demanding one. It gives a reason to open the app on a given day and a running tally of what you have finished, which suits people who like a small routine around their coloring. The stamp count also acts as a soft guide to how much of the featured content you have worked through.

The daily image is described as premium, which suggests it sits above the ordinary library in some way. Whether that means extra detail or a more elaborate design, the daily slot is clearly meant to be the highlight rather than just another entry in the list.

Weekly events and what they pay out

The app runs weekly fluid-themed activities that sit on top of the coloring itself. Finishing the coloring puzzles, cards and challenges earns rewards. The rewards named by the developer are hints and ad-free coupons.

Hints are useful in a paint-by-number game when a section is hard to read or you lose track of which number you are on. Ad-free coupons are the more interesting reward, because the game does carry ads; earning a way to set them aside for a while is a sensible incentive to take part in the events.

The events add variety to what is otherwise a single-activity app. If you only ever want to color, you can ignore them, but they are the main source of anything beyond the pictures themselves.

Saving and sharing finished work

When a picture is done, you can save it to your gallery and set it as a wallpaper. That gives the finished artwork a second life on your device rather than leaving it buried in the app, and it is a natural fit for the fluid style, which tends to look good as a background.

You can also share your creations on social media and invite other people to try the game. This is the social side of the app: just the option to show finished pieces to family and friends.

For anyone who colors as a hobby, the export options are the practical part of the feature set. Being able to keep and display what you make is often what separates a coloring app you stick with from one you delete after a week.

Who this suits

It is pitched for all ages, from children exploring fluid art to teenagers and adults after a calm pastime. The content rating is Everyone 10+, so it is aimed at a broad audience rather than very young children.

In practice I would expect the strongest fit to be adults who want a low-effort creative activity, and older kids who like the marbled look. The guided format means there is nothing to learn and nothing to get wrong, which is exactly what you want from a wind-down app.

It suits anyone who wants a calm, creative coloring activity built around fluid art effects. It is a coloring book with a particular visual style, and it is honest about being one.

A calm coloring app with a distinctive look

Fluid Art: Color By Number does one thing and does it with a clear identity. The swirling liquid effect sets it apart from the crowded paint-by-number field, and the daily image, weekly events and stamp collection give it enough structure to keep you coming back. The 4.8 average from more than 10,000 ratings suggests that structure works for the people who try it.

The trade-offs are straightforward. It is free but ad-supported, with in-app purchases available, and the events hand out ad-free coupons as rewards. The coloring is entirely guided, so the choice comes down to which picture to work on. And the whole appeal rests on the fluid aesthetic; if that look does not grab you, the underlying mechanic is the same one you have seen before.

For adults who want a quiet, undemanding creative habit, and for older children drawn to the marbled patterns, this is an easy recommendation. It is a coloring app built for relaxation, and it delivers that without asking much of you.
