warning: narrowing conversion

Hey I was trying to build this;

I downloaded the code document and added the extra libraries needed, but now it shows this:

C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.21.0_x86__mdqgnx93n4wtt\libraries\Adafruit_Circuit_Playground\utility\Adafruit_CPlay_NeoPixel.cpp:726:68: warning: narrowing conversion of '2.50332581e+2' from 'double' to 'uint8_t {aka unsigned char}' inside { } [-Wnarrowing]

Error compiling for board Arduino/Genuino Uno.

Thanks in advance for the help
