How can I find out why I have a curtain package installed (indirect dependency)?

I get these warnings:

```julia
WARNING: using deprecated binding Rotations.UnitQuaternion in KiteModels.
, use QuatRotation instead.
WARNING: KiteModels.UnitQuaternion is deprecated, use Rotations.QuatRotation{T} where T instead.
  likely near none:8
WARNING: using deprecated binding ColorTypes.RGB1 in Colors.
, use XRGB instead.
WARNING: using deprecated binding Colors.RGB1 in ImageCore.
, use ColorTypes.XRGB{T} where T<:Union{AbstractFloat, FixedPointNumbers.FixedPoint{T, f} where f where T<:Integer} instead.
WARNING: using deprecated binding ImageCore.RGB1 in ImageAxes.
, use ColorTypes.XRGB{T} where T<:Union{AbstractFloat, FixedPointNumbers.FixedPoint{T, f} where f where T<:Integer} instead.
WARNING: ImageAxes.RGB1 is deprecated, use ColorTypes.XRGB{T} where T<:Union{AbstractFloat, FixedPointNumbers.FixedPoint{T, f} where f where T<:Integer} instead.

```

Why are Colors and ImageCore in my dependencies?

```

The next question is, who can I find out which version of Colors is actually used in my test environment? Ok, I just found it in the Manifest.toml of the test environment.

```julia
version = "0.13.1"

```

`st -m Colors` in the test environment

OK, the problem was not Colors, but ColorTypes.

```julia
julia> using TestEnv; TestEnv.activate()
Precompiling project...

```

So I need to upgrade GLMakie in KiteViewers to fix this warning, I guess.
