color 0 to 255 is not consistant increase in red brightness - same for other colours.

Hi, I have four ws281 pixels installed on my board connected to GPIO pin 10. I have based my program around strandtest.py, but I wanted to address each pixel individually. But when I run the program it starts with red but at various point turns blue, I need to exclude these numbers. Can you advise a fix:
import time
from rpi_ws281x import PixelStrip, Color

LED strip configuration

LED_COUNT = 4 # Number of LED pixels.
LED_PIN = 10 # GPIO pin connected to the pixels (18 uses PWM!).
LED_FREQ_HZ = 800000 # LED signal frequency in hertz (usually 800khz)
LED_DMA = 10 # DMA channel to use for generating signal (try 10)
LED_BRIGHTNESS = 127 # Set to 0 for darkest and 255 for brightest
LED_INVERT = False # True to invert the signal (when using NPN transistor level shift)
LED_CHANNEL = 0

Create NeoPixel object with appropriate configuration.

strip = PixelStrip(LED_COUNT, LED_PIN, LED_FREQ_HZ, LED_DMA, LED_INVERT, LED_BRIGHTNESS, LED_CHANNEL)

Intialize the library (must be called once before other functions).

strip.begin()

def set_led_color(index, color):
"""
Set the color of an individual LED on the strip.

Args:
    index (int): Index of the LED (0-based).
    color (tuple): RGB color tuple (e.g., (255, 0, 0) for red).
"""
strip.setPixelColor(index, Color(*color))
strip.show()

Example usage:

try:
i = 0
while i <= 127:
# Set LED 0 to red color.
print(i)
set_led_color(0, (i, 0, 0)) # Red
time.sleep(1)
i += 1

except KeyboardInterrupt:
# Turn off all pixels and clean up resources when Ctrl+C is pressed.
for j in range(strip.numPixels()):
strip.setPixelColor(j, Color(0, 0, 0)) # Turn off
strip.show()

The solution was to increase the LED_COUNT to over 6, see other post. Now seems to be working fine.
