[ComfyUI]颜色提取插件，Flux专属，让出图更加可控

一、介绍​

今天介绍这个好玩的插件 ComfyUI APQNodes，默认的Flux模型是无法理解准确的颜色代码。​
而这个插件可以帮我忙将输入的十六进制颜色代码转换为 FLUX.1 Dev 已知的最相似的颜色名称（来自预先测试的 155 个颜色名称）。​
​
所以就可以利用它给我们的场景配色了，超级方便。​
​
先来看几张效果图，左边参考图用来提取颜色，右边成品。

二、插件安装​

插件地址：https://github.com/AIPOQUE/ComfyUI-APQNodes​
节点管理搜 ComfyUI-APQNodes​

这个插件的作用是帮忙把十六进制颜色代码转换为 FLUX.1 Dev 已知的最相似的颜色名称.​
如果你想自动提取一张图片的代码，还需要安装个很基础的插件 was-node-suite-comfyui

三、使用说明​

我们分步骤说明，先来看个完整的工作流

第一步，就是提取颜色了，这里先利用了 was插件的颜色调色板功能，如下图这样，默认是提取16个颜色，我这里改成8个就够了。这一步提取的是十六进制的颜色代码，看右下角这边输出的就是。​
​
然后利用 ComfyUI-APQNodes 插件里面的ColorPalette 节点，自动识别前面的颜色代码，转成接近的自然语言的颜色值。

下面这些颜色代码通过ColorPalette后会转化成下面的自然语言文本。

#5b1d4a​
#af4381​
#12162b​
#11355f​
#26649e​
#38a4d3​
#89a7d5​
#d1cce6

The colors are restricted to following 8 colors: plum, rebecca purple, onyx, indigo, savoy blue, pacific blue, ash gray, silver,

然后和我自己写的提示词拼起来，就凑成了完整的一个带颜色的提示词脚本了，完整脚本如下：

> This high-tech e-sports room is equipped with a powerful gaming PC featuring a transparent chassis, allowing a clear view of the intricate internal hardware. The PC is connected to an ultra-wide curved surround screen, delivering an ultimate immersive visual experience. Complementing this setup is an ergonomically designed gaming chair, ensuring player comfort during extended gaming sessions. The room also boasts a full range of peripheral equipment, including a responsive mechanical keyboard, a high-precision mouse for accurate positioning, surround sound headphones providing an immersive audio experience, a high-definition noise-canceling microphone for team communication, and an HD webcam for live streaming. Additionally, the room features an adjustable smart lighting system, e-sports-themed decorations such as posters, figurines, and team logos, a display cabinet for showcasing trophies and awards, a comfortable carpet, and a mini-fridge or snack cabinet for storing drinks and snacks. There is also a professional-grade cable management system to ensure a neat and tidy desktop. For further needs, an optional secondary screen or multiple screens can be added for multitasking, along with a beanbag or lounge area for relaxation between matches. Green plants and other decorations can also be included to enhance the room's vitality.​
The colors are restricted to following 8 colors: plum, rebecca purple, onyx, indigo, savoy blue, pacific blue, ash gray, silver, 

最后就是接入到Flux的默认文生图工作流中，去生成图片就好了。​
​
如果你觉得颜色太多不喜欢，可以用提示词替换节点，把不想要的替换成空就好了，一个不够还可以再接一个提示词替换节点。​
注意的地方，第一行颜色不能替换，不然会报错。

四、总结

以上就是颜色插件的使用啦，想要什么颜色就什么颜色，可控性大大提升。
