Context error after breaking down my project into components - GitHub Included

I am currently learning coding, step by step by doing. I built my whole UI in page.tsx, learned to utilize state hook and variables by setting up a color theme shared across multiple elements (all the blue ones). I already have the inputs with variables built up, but I'm stuck with my current problem for 2 days and can't move forward. I want to learn how to opperate with array and how to store the data, but global states are a first task for me.
I started breaking down my project into component files like the navbar (my only current componenet where the theme color is being set up). During this time I found out that I need a global variable and to utilize Context.
I tried to use chatGPT in order the use React Context. Got some code that wasn't working, then I spent some time on understanding the Context Hook - this process can be seen in my ColorContext.tsx file + sorry for the commented messy parts in page.tsx and navigationbar.tsx
After understanding it I have used chatGPT again to build it up for me and with a basing understanding of Context I tried to utilize it. At the moment I don't see any problems in the ColorContext.tsx file, but everytime I try to open the app I get the Error: useColor must be used within a ColorProvider.
The <Nav /> component doesnt even start rendering and the problem already happens on the Page.tsx. Can anyone help me understand what is causing the issue and possibly find a solution please? Is it becasuse I'm using 'useColor' already in the Page.tsx or?
Thanks a lot!

Issue solved:
The problem was that the page.tsx file was utilizing 'useColor' and was wrapped with the 'ColorProvider'
export default function Home() {
const { selectedColor, setSelectedColor } = useColor(); // usecolor called
return (
<ColorProvider>
<Button color={selectedColor} onPress={onClose}> //useColor used without it being a child of the <ColorProvider>
The solution was putting the 'ColorProvider' in providers.tsx since the 'useColor' could be called only in the children of it. This way page.tsx is a child of the 'ColorProvider'.
import { ColorProvider } from '@/app/ColorContext'
export function Providers({children}: { children: React.ReactNode }) {
return (
<NextUIProvider>
<ColorProvider>

To clarify, @Tomistoma was using the
As @Tomistoma stated, the solution was a mechanism (the above-mentioend
ColorProvider in the return of the Home page (page.tsx) and then, trying to access state values from said provider in the Home page. This does not work because the Home Page itself is not a child of the ColorProvider. As @Tomistoma stated, the solution was a mechanism (the above-mentioend
providers.tsx file) in which we wrapped the Home page and (all pages) with the ColorProvider
