Home Blogger / Plugin



Sometimes when we start to get bored with the appearance of the blog, whether it's a widget design or color size, the way to get rid of boredom is to make a few changes.
Changes that will begin to be seen usually in the colors. Then to find the type of color that we want, of course we will look for the many color picker tools available online on many sites.
What if then you want to make your own color picker tool and install it on a static blog page. This has been done by many bloggers, including the good plokis blog site itself. The reason for installing this color picker is so that we no longer have to frequently prowl to a website that provides the tool.
Here, I will share 2 different types of styles in this color picker tool. If you are interested in installing it on your blog, please choose a style that you think is suitable to be installed as a color picker tool on a static page.
