Why is this svg not affected by a filter?
This question asks to change the color of an svg using css. I had thought it would be possible to achieve this with a filter, but I'm running into a problem.
I can blur the image with a css filter, but I can't change the color. It seems that from this article, it should be possible to adjust a background-image svg's color using a filter. Where am I going wrong here?
.btn-icon
border: 1px solid black;
height: 40px;
width: 40px;
padding: 0px;
background: url("https://image.flaticon.com/icons/svg/1034/1034153.svg");
background-size: cover;
.blur
filter: blur(3px)
.color
filter: hue-rotate(40deg) saturate(0.5) brightness(390%) saturate(4);
<button class="btn-icon blur"></button>
<button class="btn-icon color"></button>

You have two main issues:
.color:
.color
hue-rotate()
sepia()
Here is an example with a filter set borrowed from another example elsewhere.
.btn-icon
border: 1px solid black;
height: 40px;
width: 40px;
padding: 0px;
background: url("https://image.flaticon.com/icons/svg/1034/1034153.svg");
background-size: cover;
.blur
filter: blur(3px)
.color
filter: invert(100%) grayscale(100%) brightness(40%) sepia(100%) hue-rotate(-50deg) saturate(600%) contrast(0.8);
<button class="btn-icon blur"></button>
<button class="btn-icon color"></button>
Thanks, I've fixed the typo. Did you see my answer? I was able to adjust the color of the image using filters, without sepia, once I had set the color of the path on the svg.

I didn't notice that it was you that answered your own question.

@Shahar had this right; it's to do with how the svg is put together. Without a fill attribute on the path, it's not possible to use color filters on the image. The raw svg has been added below, with one of the paths having color, the other not.
The filter is applied to the part of the image with the fill attribute only.
.btn-icon
border: 1px solid black;
height: 40px;
width: 40px;
padding: 0px;
background: url("https://image.flaticon.com/icons/svg/1034/1034153.svg");
background-size: cover;
.blur
filter: blur(3px)
.color
filter: hue-rotate(40deg) saturate(0.5) brightness(390%) saturate(4);
#testSvg
width: 40px;
filter: hue-rotate(40deg) saturate(0.5) brightness(390%) saturate(4);
<button class="btn-icon blur"></button>
<button class="btn-icon color"></button>

It looks like you're doing everything fine. I believe the issue is with this specific SVG file structure. I'm not 100% sure, but if the file will contain a single <path> element and a 'fill' attribute with a specific color (black could be good for a default) then it might work. At least that's one of the differences between your file and the ones in the example.
