课后反思:本课通过多种多样的学习方式,充分调动了学生的学习积极性。学单词的时候,利用实物教学,直观性强。在学习“green”的时候,我首先锻炼了学生的动手能力,让学生画了一棵树,然后再出示树木被砍的图片,让学生认识到绿

篇三:Colors 教案
篇四:Oracle DISPLAY COLOR终极解决方案
Checking monitor: must be configured to display at least 256 colors >>> Could not execute auto check for display colors using command /usr/openwin/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<<
解决 要点主要是要运行host +打通 接受控制;不是去安装啥补丁!安装啥包
如果碰到以上这个问题,就跟着下面的设置一定可以搞定!如果还是不能拿就是RP问题了。。。
1.先进入ROOT内:
su – root password:xxxxx
DISPLAY=:0.0; export DISPLAY
echo $DISPLAY
cd /usr/openwin/bin ./xhost
access control enabled, only authorized clients can connect
./xhost +
access control disabled, clients can connect from any host
2. 然后进入ORACLE su - oracle
$ DISPLAY=:0.0; export DISPLAY
$ echo $DISPLAY
:0.0
$ ls
doc response stage
install runInstaller welcome.html
$ ./runInstaller
怎么样,解决了吧!就是这么简单!!
如果包没安装请看我的另外一个文件!
篇五:Color
1.4 Color
Keeping the theme of the group in mind., a designer must incorporate in each garment a pleasing combination of all the elements of good design. These elements are color, fabrication, line, shape, and detail. One of them usually predominates in a design. These same ingredients are essential to every art form, but they alone are not a recipe for success, and they cannot substitute for experience. Fashion changes continually; there are no hard and fast rules.
Color can be the basis for a whole group or line. It is the first element to which consumers respond . People relate personally to color , usually either selecting or rejecting a garment because of its color appeal. Therefore, designers must consider their customers and provide colors that are both appealing and flattering.
People relate personally to color because it causes emotional responses, some of them based on events in their lives and on their culture. People in many agricultural countries, who have deep roots in folk traditions, have been exposed to different uses of color than people who live in business-oriented Western countries.
People connect certain colors with holidays and seasons. They expect to see the colors of autumn leaves in fall clothing,reds and greens for the winter holidays,the pastels of flowers in the spring. and refreshing white for the summer. All manufacturers include some of these colors in
their lines.
Color Selection
Every line should include a range of colors that appeals to a variety of customers. Within the line each group is usually formulated around a color plan consisting of as few as two colors or many colors. Color choices must reflect season. climate,and type of garment. Active sportswear, for example, employs much more vivid colors than spectator sportswear.
The line's color story should include some fashion colors selected from research provided by trade associations, fiber companies, or design report predictions. By basing a color story on these predictions. the designer is assured that the group will be in the mainstream of fashion. Sometimes the designer selects one or two colors from the predictions and then adds his or her own color choices to balance them. The group is then rounded out with staple colors such as neutrals, darks. white, or black. In any case. the color story must be meaningful, not just a group of unrelated colors. It might be all brights. or all muted. or a balance of darks and lights.color Relationships within a Garment.
Color Relationships within a Garment
There are several systems. all using measured scales, to guide in the selection of color combinations. Primary and secondary colors differ from one system to another. But looking at a rainbow will show you the basic
order of colors' relationship to one another.
The Brewster and Prang theories define red,yellow, and blue as the three primaries from which all other colors are derived. Mixing yellow and red paints creates orange; red and blue create purple; and blue and yellow create green the three secondary colors. Mixtures of primary and secondary colors create every color in between. The entire spectrum is often arranged into a color wheel to demonstrate the concept more clearly. However, the working fashion industry pays little attention to theories and systematic color relationships. basing selections instead on intuition and researched color forecasts.
There are no hard and fast rules for the use of colors. Rather. two colors are harmonious if they are used so that one color enhances the beauty of the other . Colors are now combined in many more unusual ways than ever before. Colors that used to be appropriate only for evening are now used also in sportswear. Ethnic influences on fashion have changed our view of color combinations, making us more receptive to new ideas. In addition. colors run in fashion cycles just as styles do. Color combinations that look right to us now will not work with the looks that are new a few years hence.
Guidelines for Possible Color Combinations Monochromatic or tonal color schemes employ varying values and intensities of one hue. (Mono means one and chroma means hue or
color. ) The resulting look is very refined. However, textural variety is needed to create interest.
Analogous colors lie next to each other on the color wheel and are related in hue. Used together, they present a rhythmic, exciting effect. An example is a combination of royal blue and turquoise (blue-green). blue being the common hue.
Complementary colors are opposite each other on the color wheel. The contrast makes both colors more intense. They may be used in equal amounts, or one color may merely accent the other. A Traditional complementary color scheme is the Christmas theme of red and green.
A triad is a combination of three colors equally distant on the color wheel. such as green. purple. and orange. This is a much more unusual color combination and is more difficult to achieve successfully. Illusions Created by Color
Color can also create illusions. For example. a garment in one color adds to the illusion of height. Warm. Light., or bright colors advance visually. making a design seem larger; cool or dark colors recede. causing the figure to look small or slender. Both intensity and value contrasts are frequently used to disguise figure problems.
Color and Fabric
Color is interpreted in the medium of fabric. If colors are chosen first. then prints are colored in the desired scheme and solids dyed to
match .sometimes,however,the fabric itself will inspire the color group.
