Question

My HTML code:

<header>
            <div class="logo">
                <img src="imagens/mascote.png" alt="" />
            </div>
            <nav>
                <ul>
                    <li>
                        <a href="#">Home</a>
                    </li>
                    <li>
                        <a href="#">Eventos</a>
                    </li>
                    <li>
                        <a href="#">Lojinha</a>
                    </li>
                    <li>
                        <a href="#">Parcerias</a>
                    </li>
                    <li>
                        <a href="#">
                            <div class="icon">
                                <img src="imagens/insta.png" alt="" />
                            </div>
                        </a>
                    </li>
                </ul>
            </nav>
    </header>

My CSS code:

*, html {
    margin:0;
    padding:0;  
}

.logo img{
    height: 100%;
}

.logo{
    height: auto;
    margin: 10px;
}

header {
    display: flex;
    margin: 0px;
    top: 0px;
    width: 100vw;
    height: 100px;
    background: #000000;
    alling-items: center;
}

nav {
    display: flex;
    justify-content: space-between;
    alling-items: center;
    margin: 30px 100px 0 600px;
    z-index: 100;
}
nav ul {
    display: flex;  
    alling-items: center;
    justify-content: space-between;
    gap: 100px;
    list-style: none;
}

nav ul li a {
    font-family: "Inter", sans-seriff;
    font-weight: 100;
    font-size: 20px;
    line-height: 36px;
    color: #FFFFFF;
    text-decoration: none;
}

a:hover {
    color: #0000FF;
  }

.icon img:hover {
    color: #0000FF;
  }
  

.icon img{
    margin: -5px;
}

Everything is working as I want, but the Instagraam icon doesn't be blue when I hover it. Why is thins happening? How can I solve this? It's because I should work with a svg icon, orcan I do this with a png? Thanks for attention.

I tried so many ways to the png color changes to blue (the original png is white), but nonehas worked, this last was my best try.

The best option seems to change the image url when hovering over it. This can be done like so:

<div class="image-container">
  <img src="original-image.png" alt="Original Image" />
</div>

.image-container {
  background-image: url(original-image.png);
}

.image-container:hover {
  background-image: url(hover-image.png);
}
