如何使用 DwmGetColorizationColor
?
文档表示它返回两个值:
- 32 -bit
0xAARRGGBB
包含用于玻璃成分的颜色,
- 一个布尔参数,“如果颜色是不透明混合”,则为 true(无论这意味着什么)
这是我喜欢的颜色,漂亮的呕吐绿色:
您可以注意到颜色是绿色的,半透明的标题栏(白色背景)非常明显地显示鼻涕颜色清楚地:
我尝试从 Windows 获取颜色:
DwmGetColorizationColor(dwCcolorization, bIsOpaqueBlend);
并且我得到
dwColorization: 0x0D0A0F04
bIsOpaqueBlend: false
根据文档,该值的格式AARRGGBB
,因此包含:
AA: 0x0D (13)
RR: 0x0A (10)
GG: 0x0F (15)
BB: 0x04 (4)
这意味着颜色为 (10, 15, 4),不透明度约为 5.1%。
但如果你真正看一下这个 RGB 值,它与我想要的鼻涕绿色相差甚远。这是
- 不透明度为零(原始颜色)的 (10, 15, 4),以及
- 白色/棋盘背景下不透明度为 5% 的 (10,15,4):
DwmGetColorizationColor
返回几乎完全透明的黑色,而不是石灰
绿色。
那么问题是:在Windows Vista/7中如何获取玻璃颜色?
我尝试使用DwmGetColorizationColor
,但这效果不太好。

我喜欢这个家伙屏幕截图比我的好得多。使用他的屏幕截图作为模板,我制作了更多火花:
对于最后两个屏幕截图,Alpha 混合芯片是真正的部分透明 PNG,与浏览器的背景混合。凉爽的! (我真是个极客)

编辑 3:现在我当然必须添加黄色。
无文档/不受支持/脆弱的解决方法
有一个来自 DwmApi.dll 的无文档导出
在入口点 137,我们将其称为 DwmGetColorizationParameters
:
HRESULT GetColorizationParameters_Undocumented(out DWMCOLORIZATIONPARAMS params);
struct DWMCOLORIZATIONPARAMS
{
public UInt32 ColorizationColor;
public UInt32 ColorizationAfterglow;
public UInt32 ColorizationColorBalance;
public UInt32 ColorizationAfterglowBalance;
public UInt32 ColorizationBlurBalance;
public UInt32 ColorizationGlassReflectionIntensity;
public UInt32 ColorizationOpaqueBlend;
}
我们对第一个参数感兴趣:ColorizationColor
。
我们还可以从注册表中读取该值:
HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
ColorizationColor: REG_DWORD = 0x6614A600
因此,您可以选择创建应用程序兼容性问题的毒药。您可以

我一年多以来一直想问这个问题。我一直都知道这是不可能回答的,而让人们真正关注的唯一方法就是拥有丰富多彩的屏幕截图;开发人员被闪亮的东西所吸引。但不利的一面是,这意味着我必须投入各种精力来制作鱼饵。
How do you use DwmGetColorizationColor
?
The documentation says it returns two values:
- a 32-bit
0xAARRGGBB
containing the color used for glass composition
- a boolean parameter that is true "if the color is an opaque blend" (whatever that means)
Here's a color that i like, a nice puke green:
You can notice the color is greeny, and the translucent title bar (against a white background) shows the snot color very clearly:
i try to get the color from Windows:
DwmGetColorizationColor(dwCcolorization, bIsOpaqueBlend);
And i get
dwColorization: 0x0D0A0F04
bIsOpaqueBlend: false
According to the documentation this value is of the format AARRGGBB
, and so contains:
AA: 0x0D (13)
RR: 0x0A (10)
GG: 0x0F (15)
BB: 0x04 (4)
This supposedly means that the color is (10, 15, 4), with an opacity of ~5.1%.
But if you actually look at this RGB value, it's nowhere near my desired snot green. Here is
- (10, 15, 4) with zero opacity (the original color), and
- (10,15,4) with 5% opacity against a white/checkerboard background:
Rather than being Lime
green, DwmGetColorizationColor
returns an almost fully transparent black.
So the question is: How to get glass color in Windows Vista/7?
i tried using DwmGetColorizationColor
, but that doesn't work very well.
A person with same problem, but a nicer shiny picture to attract you squirrels:
So, it boils down to –
DwmGetColorizationColor is completely
unusable for applications attempting
to apply the current color onto an
opaque surface.
i love this guy's screenshots much better than mine. Using his screenshots as a template, i made up a few more sparklies:
For the last two screenshots, the alpha blended chip is a true partially transparent PNG, blending to your browser's background. Cool! (i'm such a geek)
Edit 2: Had to arrange them in rainbow color. (i'm such a geek)
Edit 3: Well now i of course have to add Yellow.
Undocumented/Unsupported/Fragile Workarounds
There is an undocumented export from DwmApi.dll
at entry point 137, which we'll call DwmGetColorizationParameters
:
HRESULT GetColorizationParameters_Undocumented(out DWMCOLORIZATIONPARAMS params);
struct DWMCOLORIZATIONPARAMS
{
public UInt32 ColorizationColor;
public UInt32 ColorizationAfterglow;
public UInt32 ColorizationColorBalance;
public UInt32 ColorizationAfterglowBalance;
public UInt32 ColorizationBlurBalance;
public UInt32 ColorizationGlassReflectionIntensity;
public UInt32 ColorizationOpaqueBlend;
}
We're interested in the first parameter: ColorizationColor
.
We can also read the value out of the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
ColorizationColor: REG_DWORD = 0x6614A600
So you pick your poison of creating appcompat issues. You can

i've been wanting to ask this question for over a year now. i always knew that it's impossible to answer, and that the only way to get anyone to actually pay attention is to have colorful screenshots; developers are attracted to shiny things. But on the downside it means i had to put all kinds of work into making the lures.

着色颜色!=所选的基色。我知道这是误导。
但我很困惑。您借用的图片来自我题为“检索 Aero Glass 基色以进行不透明表面渲染”。这不是你想做的吗?我还在帖子中指出了存储所有颜色信息的注册表位置 (HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM) 以供检索之用。
已编辑 8/26
DwmGetColorizationColor (dwmapi.dll) 返回“着色颜色”,它是各种颜色(包括您选择的基色)和着色器逻辑的混合,以实现整体玻璃效果。
您需要/想要的所有颜色信息都可以在上面提到的注册表项中找到。基色、混合中使用的颜色以及最终的着色颜色都在那里。
(上面的键存在于 Windows Vista 及更高版本中。)
Colorization color != the base color chosen. It's misleading, I know.
But I'm confused. The image you borrowed was from my post entitled "Retrieving Aero Glass base color for opaque surface rendering". Is this not what you want to do? I also indicated in the post the registry location in which all the color information is stored (HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM) for retrieval purposes.
Edited 8/26
DwmGetColorizationColor (dwmapi.dll) returns the "colorization color", which is a blend of various colors (incl. your selected base color) and shader logic to achieve the overall glass effect.
All the color information you need/want can be found in the registry key noted above. The base color, the colors used in blending, and the resulting colorization color are all there.
(The key above is present on Windows Vista and above.)
我相信我已经解决了 Aero Color。 ColorizationColor 给出的颜色实际上是 AARRGGBB,但它根本没有按照您想象的方式使用。为了解决最终的颜色,您还需要获取颜色强度,如下所示: http://www.codeproject.com/Articles/610909/Changing-Windows-Aero-Color
第一步是解析 AARRGGBB。然后将生成的 RGB 转换为 HSV。纯色相加上全亮度饱和度是基色。现在将值作为 Alpha 的灰度叠加在纯色相和饱和度之上,以获得 Aero 颜色。然后将该颜色叠加在帧颜色上:强度为 rgb(235, 235, 235),以获得最终的 Composite Aero 颜色结果。
最后,我还提供了一个示例,说明如何提取与 Aero 框架颜色相匹配的可用工具栏颜色,但始终适用于黑色文本和其他基本 Aero 功能。这是通过将强度限制为 35% 来实现的。
这是数学:
I believe I have solved the Aero Color. The color given by ColorizationColor is in fact AARRGGBB but it is not being used in the way that you think at all. And in order to solve the final color, you also need to get the Color Intensity as shown here: http://www.codeproject.com/Articles/610909/Changing-Windows-Aero-Color
First step is to parse AARRGGBB. Then take the resulting RGB and convert to HSV. The pure Hue plus Saturation at full brightness is the base color. Now overlay Value as a grayscale at Alpha over top of pure Hue and Saturation to get the Aero color. Then overlay that color over the frame color: rgb(235, 235, 235) at Intensity to get the final Composite Aero color result.
Lastly, I've also provided an example of how to extract a useable toolbar color that matches the Aero frame color, but will always work with black text and other basic Aero features. This is accomplished by limiting Intensity to 35%.
Here is the math:
