Under the limit of a total of 16 colors, ascii operation How to make an art colorful? Through the recent short summary of color, the following stuff will be used as a reference for everyone, and I also hope that Can arouse more people's interest in ascii art and join us 1. Application of basic colors Red: Passionate, lively Yellow: Warmth, stability Green: Moderate, natural Indigo: cold, chill Blue: calm, melancholy Purple: dreamy, romantic White: bright, pure Black: mysterious, serious I believe everyone can see the above in different tutorials, but why should I take it out? Because I I feel that these two pictures are a very condensed summary of the basic use of color. All the foreground colors and background colors are given above. The combination of scenery. The following is a summary of the meaning of basic colors that I think is very accurate. I like it very much. Often realize its true meaning on different occasions In addition, many people may have noticed that the color arrangement of the two pictures above is a bit particular. That is to say, they are arranged according to the chromatographic order of red, orange, yellow, green, blue, and violet. This is not true in terms of the control code numbers. Same, this may not be important for general coloring, but if used in more advanced situations, than For example, it is particularly important to know a little bit about this aspect of time-lapse animation, which will make the animation appear smooth and impressive. Maybe after seeing the above stuff, everyone will feel bored and lose confidence in the monotony of ascii colors. However, in fact, the ascii world is far more than that monotonous, which is where its art lies. Although the basic colors are so monotonous, there are still many things to explore, such as the following example FLASHFLASHFLASHFLASHFLASHFLASH FLASHFLASHFLASHFLASHFLASH FLASHFLASHFLASHFLASHFLASHFLASH FLASHFLASHFLASHFLASHFLASHFLASH In this example *[30m gray reflects a transparent effect 2. Color expression level For basic color control, there are only two levels: high brightness *[1m and low brightness *[0m. But through a If you have certain skills, you can break through this limit. Don’t you believe it? Read on. The first thing mentioned is the problem of white. Other colors have two levels of brightness, but white is an exception. It actually has four or three color levels This is actually the reason why many prawns favor it. The three types of white will be mentioned again later. The magical uses of gray 1 virtual reality Using virtual and real lines and graphics in ASCII code can create more levels. Examples are as follows 2 thickness The same effect can be achieved through the thickness of the line In fact, in the example above, the grayscale of the thin lines I used is even lower than the thick lines, but it gives people the visual The senses are gradually changing 3 Size and density Using the size and density of dots, you can also construct multiple levels of realms. Examples are as follows: Here's another example: :::﹕ ::::::﹕ :::::: : The color is still high-bright and low-bright, but it gives people the feeling of more layers. 3. Color expresses three-dimensionality 1 Representation through shadows like The above example is a typical three-dimensional effect using black shadows. The following is the above example. Improved version: LoVeloVeLOveLoveloveLoVE lOvElove velovelOve LoVELove love veLovELOvE LoveLOVE velOVEloVe LoVeloVeLOveLoveloveLovE LoveLOveLoveLOVEloveLoVe Why does this one look better than the last one? It's because actually the shadow cast The blue background is not pure black, but a natural pattern is added to the background to play a role in the color. It has a certain buffering effect, so it looks better. It’s amazing, right? Here's another example of shadows zooming out for seamless viewing Here a *[1;30m gray is used to reflect the shadow. In fact, some other low-bright colors can also be used as shadows. 2 By highlighting Here are a few examples of zooming out the screen for seamless viewing This is the most common means of expressing a three-dimensional effect. For specific methods, please refer to relevant articles. 3 Representation through relief I don’t need to explain the effect of the relief here. I think everyone can understand it at a glance. Understand the truth behind it. The main thing is the control of light and shadow, but you have to pay attention to it. It means that most people's perception of light is from left to right, so it is convex Concave This example illustrates the use of white in one 4 Through virtual and real performance Here is just a comprehensive example Three years later, on Chinese Valentine's Day There will be a heavy rain This example uses a very interesting set of background patterns, using the thickness of the lines and the depth of the colors. And the blank virtual reality constitutes a three-dimensional layered effect. 4. Color expresses texture 1 transparent By Yijiangnan㊣ Transparency mainly uses the principle of complementary colors. I won’t go into details here. If you are interested, you can read some related articles. 2 metal In fact, white and yellow It itself represents a certain metallic texture. Let’s look at an example below. Zoom out the screen to watch seamlessly. Right angles and squares often create a metallic look Such as the box below 5. Color expresses line thickness As mentioned earlier, we use the thickness of lines to express color. In the same way, we can also use color to express thickness. 6. Color expresses special effects There are many such effects, and there are still many to be explored. Here is just one of the most commonly used water reflection effects. It's actually very simple. Highlight and lowlight can just show the reflection effect properly. I remember once seeing an ASCII work. It was a reflection of a huge moon in water. The effect was very shocking. Let’s stop here. Having said so much, I would like to mention a sentence that I like very much about ascii art. Art breaks through the limits. I don’t have much time to do ASCII. I do less and read more. My own works now seem almost useless. There is a satisfactory work. Perhaps it is as the saying goes, "Three Thousand Waste Paintings" were found by chance. I also got some small details in some works. Experience and insights, deep enjoyment of it, including understanding and experience of some special characters. Let me sort this out. I will share it with you next time. It is worth mentioning that I came up with the sentence above. I have also experienced the hardship of making color block diagrams, but With software like bmp2ascii, it brings us to think about where the ascii art is, whether it is a color block Pictures have no meaning. In fact, this is not the case. Any art form depends on its tools and means of expression. Otherwise There will be no place for it. Then the essence and essence of ASCII art is the limitations of its characters and colors. If there is no such If there are some limitations, then I think ASCII will no longer be ASCII. So a classic ASCII work should have these limitations. I believe that everyone has a work that shows the most vivid and even breakthrough in production. I believe that one character and color can be the finishing touch. The experience of using it is also reflected in the color block diagram, so software still cannot replace people. In addition, I would like to mention another feature of ASCII, that is, whether it is a signature, description or various pictures, there is one feature It is the mind that is the soul I feel really ashamed from doing ASCII to now. I have hardly made any big discoveries. But I hope everyone can work hard together. Power makes the world of ascii colorful It took almost a night to complete this article. It is inevitable that it will be superficial, but I have suppressed it for so long and finally let it out. It’s just quick, but I really hope it can bring some help and interest to beginners. In this way, the purpose is achieved. *Some of the examples used above are taken from the works of other people. I would like to express my gratitude to you.
