What Is a Colorful List Creator?

This online utility adds colors to list items and displays them as a PNG picture. The program can simply create a neat and colorful illustration of all the items or create a visualization that groups by color the repeated items and visually separates the unique items and duplicate items. It's super helpful when you need to quickly see the structure of your list visually as color conveys the information instantly. For example, if you have a to-do list and you want to make sure no tasks are repeated in it, you can color just the repeated items and instantly see which tasks were entered twice. You can load any list of items in the input and indicate which character (or several characters) is/are used as the item separator. The separator can then be specified using a symbol or a regular expression in the options. You can also enter a different character for the output list and it will serve as an item separator in the multi-colored image. In the second block of options, you can find four visual modes. The "Use Different Item Colors" mode colors the list items with different colors. Each item gets a unique color from the rainbow palette (going from red to orange to gold to green to blue to indigo to violet). The "Highlight the Same Items" mode helps you quickly find equal items in the list. Identical items are painted in the same color, thereby visually grouping them. In the "Highlight Unique Items" mode, the unique items will get highlighted and any repeating items will be grayed out. And the last mode, "Highlight Duplicate Items", uses colors for all duplicate items. In this mode, the first occurrence of an item remains gray and a repeated occurrence has a color. To customize the output canvas, you can set its dimensions, item size, and positioning. Namely, you can set the width and height of the image, specify the font size for each item, line height, padding around the image, and align the items to the left, right, or center. The picture of the multi-colored output list items can be downloaded from the output preview window. Listabulous!

Create a Colorful List of Numbers

In this example, we create a colorful illustration from a list of integers from one to one hundred. We use a comma to separate the input and output items and activate the rainbow colors drawing mode. We also set the illustration to a fixed width of 725px, add 10px padding (as a border), set the font size to 48px and line-height to 50px. As a result, we get an image of all the numbers with their color having a rainbow color gradient.

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100

Find the Same Picture Game

In this example, we want to create a game called "Find Two of the Same Picture". To create this game, we pick interesting Unicode glyphs and emojis, load them into the input, and separate them by the regular expression "/[,;]\s*/" (since there is either a comma or a semicolon between the items). To make it visually easier to find two identical pictures, we paint them in the same color using the "Highlight the Same Items" mode. We place the items for the game on a square 330 by 330 pixel canvas and center them.

Highlight Unique Types of Nuts

In this example, we use the list coloring algorithm to find the unique items in the list. We load a list of various types of nuts, separate them by a newline character and switch to the "Highlight Unique Items" mode. In the output, we get an image of the list, which has unique items painted in bright colors and repeated items that have a neutral gray color.

Color Duplicate List Items

In this example, we want to find all duplicate items in a list of essential vitamins. We split the list items by a comma and use a space character for the output list. We choose the "Highlight Duplicate Items" mode, set the image width to 440 pixels, and add 10-pixel padding on all sides. As a result, the items that are mentioned a second, third, or more times are highlighted in bright colors but their first occurrence is left gray.

A, A, A, C, C, C, C, D, D, E, E, E, E, K, K, K, K, B1, B1, B1, B2, B3, B3, B3, B6, B6, B6, B6, B12, B12, B12, B5, B5, B5, B5, B7, B7, B7, B9, B9

Create a Multicolor Grid

In this example, we create a fun multi-colored grid. To do this, we load a list of Unicode block elements and as there are no separators between the blocks, we use the regex "//" to find each Unicode glyph. We set the canvas to a fixed size of 361 by 400 pixels and draw all the blocks in different colors. Thus, we get a QR code-like picture that shimmers in the style of a rainbow.

Color a Todo List

This example adds colors to a summer todo list. As we spent all winter waiting for the summer, we accidentally wrote down the same items in the list. To quickly see only the unique things we want to do this summer, we use the unique item coloring mode.
