Colorful Hearts in FTB Skies 2: Aero

Same as in the All the Mods 10 8.1 guide

Colorful Hearts is a small client-side mod that changes how your health bar looks. Vanilla stacks extra rows of hearts once you pass 10 hearts of health or absorption. This mod replaces that with a single row, and each "layer" of health or absorption gets its own heart color.^[1]

It also adds half-heart background textures. If you only have half a heart of absorption, the black bordered background covers just the left half of the icon, so it no longer looks like something is missing on the right.^[1]

This pack ships Colorful Hearts 10.5.9, built for NeoForge 1.21.1. It has been in the pack since version 2.25 or earlier.^[2]

Who it's for

It's for anyone who ends up with a lot of health or absorption and wants a tidy, readable bar instead of towers of hearts. Because it's client-side, it only changes what you see on your own screen. You can customize the colors with a list of hex #RRGGBB values in the mod's config file.^[1]

Compatibility notes

The mod lists built-in support for several other mods. AppleSkin shows the potential health restored by the food you're holding. Raised moves the hearts correctly. Farmer's Delight gets a working comfort overlay, The Undergarden a working virulence overlay, and Eidolon:Repraised a working chilled overlay.^[1]

Unverified No in-pack guidebook, quests or ATM Star path entry for Colorful Hearts could be confirmed, so this guide does not describe a progression stage for it. Treat it as a quality-of-life display mod that works from the moment you start playing.

Good news: there's nothing to craft or unlock to get going with Colorful Hearts. It's a simple client-side mod, so it works on your own game's display and doesn't add gameplay content you need to build up to.^[1]

What changes on your screen

In vanilla Minecraft, once you have more than 10 hearts of health or absorption, the game stacks extra rows of hearts on your HUD. Colorful Hearts replaces that renderer. Each row of health or absorption is shown as a differently colored heart instead, so your health stays in a single row.^[1]

It also adds half-heart background textures. If you only have half a heart of absorption, the black bordered background covers just the left half of the icon instead of leaving a black gap on the right as if something were missing.^[1]

Your first steps

1. Play normally and watch your health bar as you gain extra hearts or absorption. The color of the heart tells you which row you're on.^[1]
2. If you want different colors, change them in the mod's config file. It takes a list of hex #RRGGBB values.^[1]
3. If you run other HUD mods, check the compatibility list below before you start tweaking things.^[1]

Compatibility to know about

The mod lists built-in support for AppleSkin, Raised, Farmer's Delight, The Undergarden, Overflowing Bars and Eidolon: Repraised. For example, with AppleSkin you get a preview of how much health your held food would restore, and with Farmer's Delight the comfort status effect overlay works.^[1]

Unverified Whether this pack changes the default heart colors, and whether the pack includes every mod from the compatibility list, could not be confirmed from the available sources. This guide also found no in-pack recipes or quests for this mod, so there are no recipe steps to show here.

Colorful Hearts has no machines, multiblocks, power, fluids or item handling to automate. It's a client-side mod that only changes how your health bar is drawn, so everything in this section is about the heart display.^[1]

What it replaces

Vanilla adds more rows whenever you have more than 10 hearts of health or absorption. Colorful Hearts replaces that renderer. Instead of stacking rows, it keeps a single row and uses a different color for each row of health and absorption.^[1]

The mod also adds half-heart background textures. If you only have half a heart of absorption, the black-bordered background covers just the left half of the icon. It no longer looks like something is missing on the right.^[1]

Colors and configuration

The row colors are set in a config file that takes a list of hex #RRGGBB values. The sources don't list the pack's actual color values, so check in-game to see what you get.^[1]

Unverified Whether this pack ships a Colorful Hearts config file, and which colors it uses, couldn't be confirmed from the available sources.

Compatibility with other mods

The mod's project page lists extra support for several mods: AppleSkin shows the potential health restored by the food you're holding, and Raised moves the hearts correctly. Farmer's Delight gets a working overlay for the comfort effect, and The Undergarden gets one for virulence. Eidolon:Repraised gets a working overlay for the chilled effect, and its ethereal health renders normally after the health and absorption hearts.^[1]

Good news first: this pack ships Colorful Hearts with every config value left at the mod default, so nothing here has been retuned behind your back. That means the config is purely a cosmetic playground: tweak it to taste, or leave it alone and get the stock look.^[3]

All of the settings live in one file, and every color option takes a list of hexadecimal RGB values written in the '#RRGGBB' format.^[1][3]

Health row colors

health.colors sets the color used for every 10 hearts of health, not counting the default red first row. The pack uses the default list of ten colors: #F06E14, #F5DC23, #2DB928, #1EAFBE, #7346E1, #FA7DEB, #EB375A, #FF8278, #AAFFFA and #EBEBFF. If you want your second health row to be something other than orange, this is the line to edit.^[3]

The status-effect variants are separate. health.poisonedColors is #739B00, health.witheredColors is #0F0F0F, and health.frozenColors is #3E70E6, all pack values matching the mod defaults. These normally take two alternating colors, but a single color is allowed if you want the vanilla-style effect heart.^[3]

Absorption row colors

Absorption gets its own matching set. absorption.colors covers every 10 hearts of absorption with the pastel default list: #E1FA9B, #A0FFAF, #AAFFFA, #AACDFF, #D7B4FF, #FAA5FF, #FFB4B4, #FFAA7D, #D7F0FF and #EBFFFA.^[3]

• absorption.poisonedColors alternates between #BFF230 and #7AA15A.^[3]
• absorption.witheredColors alternates between #787061 and #73625C.^[3]
• absorption.frozenColors alternates between #90D136 and #36D183.^[3]

Turning the hearts off

health.vanillaHearts and absorption.vanillaHearts control whether vanilla hearts are rendered. Both are set to true in this pack, which is also the mod default.^[3]

FTB Skies 2: Aero 1.10.0 ships Colorful Hearts 10.5.9, the NeoForge build for Minecraft 1.21.1. The mod has been in the pack since Aero 1.0.3 or earlier.^[4]

Colorful Hearts 10.5.9

This is the version you have in 1.10.0, released on 2025-07-31. Here is what the mod's own changelog lists for it:^[4][5]

• Fixed a possible crash when hearts might not be calculated in the AppleSkin compatibility.^[5]
• Fixed Overflowing Bars compatibility. The changelog notes it still requires manually disabling allowLayers for health inside the Overflowing Bars config file.^[5]
• Added Farmer's Delight Refabricated compatibility.^[5]

Unverified No pack changelog entries mention Colorful Hearts, so any changes to it between individual Aero releases are unverified.
