rgbterminal 0.3.0

A Python library for terminal-colored text with 256-color and truecolor support

Terminal text coloring with RGB and multi-stop gradients in Python.

---

Features

• Color text using truecolor (24-bit) or 256-color approximation
• Multi-stop gradient text with smooth interpolation
• Reusable factory classes for fast generation
• Animated gradients with time-based looping
• Pure Python — only depends on numpy

---

Installation

pip install rgbterminal

---

Usage

Basic RGB Text

from rgbterminal import RGBText

text = RGBText("Hello World!", rgb=(255, 0, 0), truecolor=False)
print(text)

RGBTextFactory

from rgbterminal import RGBTextFactory

factory = RGBTextFactory(rgb=(0, 128, 255), truecolor=False)
text1 = factory.t("Hello")
text2 = factory.t("World")
print(text1, text2)

Gradient Text

GradientText allows you to apply a smooth gradient across a string using multiple color stops.

Multi-stop Gradient Example

from rgbterminal import GradientText

gradient = GradientText(
    "Gradient Example",
    rgb_stops=[(255, 0, 0), (255, 255, 0), (0, 255, 0), (0, 0, 255)],
    truecolor=False
)
print(gradient)

• Supports any number of RGB stops.
• Interpolates colors in HLS space for smooth transitions.
• Works with both truecolor (24-bit) and 256-color terminals.

GradientTextFactory

from rgbterminal import GradientTextFactory

factory = GradientTextFactory(rgb_stops=[(255,0,0), (0,0,255)], truecolor=False)
text = factory.t("Hello Gradient!")
print(text)

• Factory allows you to reuse the same gradient multiple times.
• You can override stops per call if needed.

Animated Gradients

The new animated_gradient_print function animates a smooth, cyclic gradient across text in real time — perfect for banners, CLI logos, or loading indicators.

import time
from rgbterminal import GradientText, animated_gradient_print

gradient = GradientText(
    "Animated RGB Terminal!",
    rgb_stops=[(255,0,0), (255,255,0), (0,255,0), (0,255,255), (0,0,255)],
    truecolor=False
)

animated_gradient_print(gradient, duration=5, fps=30, speed=1.0, resolution=12)
